The Wilson Inlet sand bar has been artificially opened each winter since the 1920s to limit flooding of low lying lands adjacent to the Inlet. Once the Inlet water level reaches 1.01 m above AHD, the bar is breached by cutting a channel through it with an excavator.

The diagonal protects the trench until the trench digs itself deep enough and wide enough to prevent the waves from stopping it up again..... When it gets really strong and wide outflows it obviously straightens up... it's big enough then to do what it wants and can't be overpowered by the waves.
The line points directly into the inlet, which flows around and to the right. If you look at Wilson’s Inlet on Google earth you’ll see it’s not diagonal at all. The sand bar is diagonal, the trench goes into the inlet perfectly virtically. If they dig the trench the way you describe, in a straight line from the beach, the water in the inlet would have to do a weird 90° turn to get to the ocean.

LOLOL We're only doing what guys have done for years while looking through the fences into a construction site and putting in their 2 cents worth of sage advice.
For laughs I tried to put some math into the idea of people shoveling it out in a big dig-fest. If you assume 8 shovel scoops per ft³ its 216 a yard. Even numbers, 200 scoops per yard, a 2 yard bucket is 400 and if he's keeping an average of 4 scoops a minute thats 1600 shovels per minute. Say a person will average 2 a minute when you figure they're not keeping a non-stop pace, so 800 people digging at all times and they all have to eat, drink, use the bathroom, get there, get organized, manage not to get hurt in unstable sand digging a 4 foot deep trench with no boxes. Seems totally reasonable, much cheaper than a few guys supervising an operator and a couple of surveyors....
The inlet is now an outlet. 🙂 It's a good example of the power of water. Nice work. If this were filmed with a helicopter with a gyroscopically stabilized camera mount, it would have cost thousands of dollars.
Can anyone provide a brief explanation as to why this occurs? And how long it takes for that bright blue beach to return to its self? prior to the dark and brown water making it look much less appealing.
I am no Oceanologist, but I believe this has to do with wave and tidal actions from the Ocean bringing up and depositing sand at the inlet. One of the sources for an estuary is rainfall and runoff from uphill which will vary over the seasons, during the dry seasons the estuary would have low or no outflow. Because there is low outflow wave and tidal actions are able to wash sand ashore and nothing pushes it back out to sea. Big storms coming ashore also contribute with their winds blowing the water and sand toward land. Over the seasons a bar is created and the bodies of water separate. Sand bars will breach on their own given enough time, usually during a shore side flooding event, but in this case since there is Human infrastructure near flooding intervention was needed. As for the bright blue beach returning, it would vary based on the factors contributing the sand bar in the first place, or how low the estuary empties during the breaching process. Probably a week or two. Once the estuary lowers and the outflow slows enough the brown water would dissipate into the blue water to the point where you'd never notice it. If I were part of the decision making team, I would time this draining to begin a few days before an unusually low tide so that the estuary empties as much as possible, but also does not entirely back fill with sea water. This would give the Ocean a good head start on building another sand bar that would likely last several years. For what it is worth the brown color mostly comes from decaying plant materials in the water, it is ugly but completely harmless (except for the inevitable Human environmental runoff). Not really brief, but I have a habit of turning as many stones as possible. Hopefully this helps.
It is dug when some farmland around the inlet becomes flooded. The large reduction in the annual rainfall in the south west of Oz means it doesn’t get the large volumes rushing into the estuary to create a natural break. It has recently remained opened over a year due to Denmark and surrounds receiving their old average rainfall in 2023 for the first time in many years
Yep, marginal flooding of land can just be seen in some of the aerial shots of the estuary. It would have been interesting if the video maker had pointed that flooded land out with captions and told us the difference in the impounded estuary water level and the tide levels before the bar was breached.
I can only imagine the uncontrollable excitement experienced by the excavator driver on his painstakingly slow drive, back to remove the plug. One must admit to pissing himself slightly, such was the anxiety. And I was on x2 playback
The brown water is fresh, but brackish and brown from peat. It's cheaper, by far, to send out an excavator once a year than it is to build some kind of permanent structure, and structures require maintenance on a regular basis, which is even more expensive.
@@mikem631and the basis of "needs 1 foot" is what research exactly? You sure know the banks can collapse into a channel, slow down flow and prevent the self-widening? Show that you did think about that, quantitatively
People, people, people. The guys in the safety vests with the trucks are the engineers, environmental folks etc. They specified the sizing and shape of the trench. Give the excavator operator a break. He is simply meeting the specifications......
Every other country uses a boogie board, a convenience store shovel and gravity for the project. No hard hats, just a lot of excitement as the sides of the sand are cleaved away by the ever increasing flow
I grew up near Glenrock Lagoon in NSW. The lagoon cyclically fills, washes open across the beach, builds the sand back up and repeat. It seems odd that this one doesn't open by itself.
It does, I went fishing down here years ago and the winter rains used to break through it maybe they’ve had a bad year rain wise. But regardless, this should be left to nature to sort out because these cycles are normal. The snapper grow up in there and when it breaks they are met by the sharks on the other side, meanwhile it’s great fishing before this happens.
Some explanation would be useful. Presumably the freshwater lake is fed by a river which eventually will be surrounded by mud flats when fully drained. Will this provide a wildlife habitat or is this an engineering solution to free up an area for future land use?
Yes, the Denmark River and other streams flow into the Wilson Inlet. Flow is dependent on rainfall alone, and this is mainly in winter. Good rainfall is required to breach the bar. The road and low-lying areas around the estuary/inlet would flood if the bar was left to breach naturally. When levels have dropped the sand bar rebuilds to several meters above sea level, closing it off from the ocean. This can take days to several months.
Shoreface948 Its an amazing video and the excavator did a very professional job. I enjoyed watching very much. I would however like to know the purpose of joining the estuary and the sea like they did. It would complete the story for me, Thanks 😊
When the lagoon backs up with water especially flood waters in winter... it destroys valuable land etc further back upstream... and we can't have that mate... we pay rates... dig that channel!
Maybe you tell those guys with the degrees and the experience of doing it on a semi-annual basis. I'm sure they'll realize the error of their ways and hold digapalooza next year. A few man buns with beach toys and it'll be open in mere minutes. There's no way that a 25 ton machine can beat some groms with sand toys.
@@JohnSmith-pl2bkdu brauchst im Prinzip nur einen ganz kleinen Graben, durch die Strömung vom Wasser wird immer mehr und mehr Sand mitgerissen und wird von allein zum Fluss... Da verstopft nix wenn der Graben erst einmal fließen kann😅 Die Leute aus dem Video haben als Kinder nie im Sand am Meer oder Badesee gespielt und Gräben mit Wasser frei gespült 🤷♀️
@@kleinerstubentiger The sandbar didn't just materialise...the strong wave action caused it to accumulate...and a small ditch might have been overcome by the wave action before achieving a full scoring flow of water. They do this every year. have done for 100 years. I bet they know what they are dong...
Awesome shots !! I love how creative the drone shots were are able to create. It’s an amazing tool for creating!! And the pilot has the ability to create their own vision into reality!! Subbed my friend!
They make it double wide so the sides don’t crowd the excavator. They’ve been doing this every year for over 100 years, trust that they know what they’re doing.
Before digging the plug, it kinda reminds me of the Suez Canal from Goggle Earth. I imagined them putting in miniature locks on it. Row boats and swan paddle boats paying 50 cents to pass through each lock on the "canal". LOL I don't know where my mind goes sometimes...apparently some hydrological Mr. Rodgers Neighborhood. HA! Looks like the operator was in his own world too. He built as much tension as he could dragging out the last few buckets. Maybe the operator was thinking "And Moses stretched forth his hand over the sea, and the sea returned...".
The Ayatollah of Rock and Rollah makes a good point. The only reason they should have that many engineers is to make a permanent lock system to do this each year.
As far as I can see, the excavator driver is taking a simple job and fleshing it out into two days work for very little reason. The sediment all appears fine and mobile, and the water level in the estuary is higher than the ocean. So all you actually need to do is to make a trench about a foot wide through the sand bank blocking the bay where the bottom of the trench is just below estuary water level and the water flow will then do everything else for you once you breach the sandbank. Of course this is a mere half day of work on a mini-digger and the operator doesn't get to make a completely unnecessary freshwater trench and also doesn't get to put in a nice curve and all that stuff (which disappeared as water eroded it) so his enjoyment is likely diminished, but it does save you a fair amount of machine time.
I was thinking something similar. Bring in a D-7 CAT bulldozer and just clear a line from the estuary to the ocean till it's lower than the estuary, then let nature take it's course.
He's just digging the size and shape of trench he's been instructed to. Sheesh, you armchair experts have got the poor bloke tarred and feathered and you haven't even raised a sweat!
@@SafeTrucking No, not the operator, the bosses that hired him. Yeah, he's just doing his job. But the designers of the project are the ones that appear not to have really thought this thing through. Lots of simpler ways to get it done. For instance, they didn't really need a plug between the estuary and the channel. Just keep digging the channel with the water in it. At some point, it will be lower than the estuary and nature will take over. No need to dig all the way to the ocean like they did.
Come on everyone, who wouldn't love to play in a big sand pit with a real Tonka tuff digger like that. Im surprised he didn't stretch it out to a week.😂
Before they did that dig they 100% did a extensive repot of why its neeeded, tidal range energy input can help ecosystems alot. The brown water is i assume cus of the lack of oxygen.
The planet managed by flooding the area where people have now built buildings and roads, until the flooding breached the sand bar itself. In other words this is a man-made problem.
@@-Gorby- actualy not. The riverbed continues in the sea. And it was all-year draining until 6000 years ago when Aboriginal Australians decided to close it for fishing in the winter. Even today after the water drops it remains small channel that humans close on pourpose every year. This raises the lake very slowly during the non-rainy season year and it breaches(usually by itself) however it does not close by itself.
If they're doing this every year I would have to guess that the ocean is putting all that sand back with the tides. Cuvert wouldn't work because of this
Hi, @cameroonkendrick6312. And just where would they/you build these dunes so that they a. would not wash or blow back into the bar area? b. would not destroy any existing landscape or environment? c. would not interfere with recreational access to the area? A 'kew-ree-yuss' mind would like to know. Just my 0.02. You have a wonderful day. Best wishes. Deas Plant.
Okay, so exactly why does this inlet silt up like this? Is it a heavy sand load of the river? Or do currents force the sand to pile up? Why does it close that way?
@@JohnSmith-pl2bkCan stand comments like this. Someone is genuinely curious about the video and wants to hear from likeminded people and some dumb-arse in the comments is like “just look it up yourself 🤡”.
Or instead of wasting money on a dozen public works people sitting around twiddling their thumbs and an excavator, put out an announcement that the beach is ready to be breached and get some food trucks on the beach, make it a party and people from all over would come to dig it out for free.
1 worker in the digger, 4 geologists, 2 Marine environmentalists, two surveyors and one poor sap to put in poles to do with elf and safety to keep the crowds away...
Actually this is a common phenomenon...it's completely natural. The tides silt up the river mouth naturally and when either a storm breaks the dike or the water behind it over-tops the bar it flushes itself out. As soon as the water is low enough, it will silt itself up again and start all over again.
@@pastorjerrykliner3162 Except where I live, they diverted the river for a railway, slowing its flow and preventing scouring. So the valley floods - but they've just spent millions on a new bridge to span the flood that has been delayed because the valley floods making bridge construction difficult !
Why did they dig the initial channel so diagonally? It was orobably 3 or 4 times longer than needed to be. Then nature takes over and says.... yes, straight line please.
I haven't been to Denmark the country,but I have been here and it's an amazing place and I can only guess someone who knew of Denmark before named it.

@@karlchristoffer1275 I'd have to win lotto😂😂I live on the central coast in Queensland now,no real beaches unless you head out to the reef but still a nice consolation prize with its weather
Am I correct in assuming that the water is black/dark like that is because of all the organic material decomposing in the saltwater also no circulation and movement of water flow.
Kinda makes it look like the sea levels are dropping, not rising. Whats with the diagonal trench? Waste of fuel and time compared with a more direct trench.
@@BTW...you have to dumb down measurement into multiples of ten cause you can't count to 12 without taking a shoe off but you're giving lectures on spelling based on the location of the video not the commenter? If it weren't for people who spell it meter the context would involve Japanese characters...
The diagonal protects the trench until the trench digs itself deep enough and wide enough to prevent the waves from stopping it up again..... When it gets really strong and wide outflows it obviously straightens up... it's big enough then to do what it wants and can't be overpowered by the waves.
Am I the only one that sees this as inefficient? Three bulldozers working at gaps of several hundred metres just pushing the soil across in to a pile would be far faster than a single digger swinging back and forth?
@shoreface I nearly missed this altogether! How? Well these videos are put out on the WORLDWIDE web and if you want folk to watch them ....... Even 'WA' in the title would've helped.

Sand bars will breach on their own given enough time, usually during a shore side flooding event, but in this case since there is Human infrastructure near flooding intervention was needed.
As for the bright blue beach returning, it would vary based on the factors contributing the sand bar in the first place, or how low the estuary empties during the breaching process. Probably a week or two. Once the estuary lowers and the outflow slows enough the brown water would dissipate into the blue water to the point where you'd never notice it. If I were part of the decision making team, I would time this draining to begin a few days before an unusually low tide so that the estuary empties as much as possible, but also does not entirely back fill with sea water. This would give the Ocean a good head start on building another sand bar that would likely last several years. For what it is worth the brown color mostly comes from decaying plant materials in the water, it is ugly but completely harmless (except for the inevitable Human environmental runoff).
Not really brief, but I have a habit of turning as many stones as possible. Hopefully this helps.
@@aland7236 outstanding response and info mate. Thankyou.
@@lonewolf6364 With pleasure my friend.
It is dug when some farmland around the inlet becomes flooded. The large reduction in the annual rainfall in the south west of Oz means it doesn’t get the large volumes rushing into the estuary to create a natural break. It has recently remained opened over a year due to Denmark and surrounds receiving their old average rainfall in 2023 for the first time in many years
Yep, marginal flooding of land can just be seen in some of the aerial shots of the estuary. It would have been interesting if the video maker had pointed that flooded land out with captions and told us the difference in the impounded estuary water level and the tide levels before the bar was breached.
Oddly satisfying. Thank you for taking the time to record this video!
JOOG SQUAD will have that done in the morning ready for an afternoon session..
That's what I was thinking too! @joogsquad would have saved the people of Australia a mint.
I can only imagine the uncontrollable excitement experienced by the excavator driver on his painstakingly slow drive, back to remove the plug. One must admit to pissing himself slightly, such was the anxiety. And I was on x2 playback
Anyone take a ride along the channel on a board or dinghy? Looks like fun!
That's what I stayed to see !
'kin ell that snare drum woke me up!!! Amazing video!
this! i was having some catharsis then wham! whats going on ?
The music is a bit over the top.
is the brown water fresh or salt? what if yall dredged it permanent or put in a giant pipe or lock?
The brown water is fresh, but brackish and brown from peat. It's cheaper, by far, to send out an excavator once a year than it is to build some kind of permanent structure, and structures require maintenance on a regular basis, which is even more expensive.
@@r.awilliams9815 ok thanks. i was just concerned about the risk of losing a $100k machine and/ or salt damage
i can only assume the digger operator was on an hourly rate cos that was wayyyyyy more digging than needed
a father-son team did it in 1 day hand digging a trench...
Thats exactly what I was thinking. 2 buckets wide when it only needs to be 1 foot.
@@mikem631and the basis of "needs 1 foot" is what research exactly? You sure know the banks can collapse into a channel, slow down flow and prevent the self-widening? Show that you did think about that, quantitatively
It’s a council excavator and the operator is a council worker. Just a days work…
o so he is working way to fast for a Gov employee. unless that was a 6 month project. @@TheG1162
I wonder if any of these experts read the description. Nah, that would make too much sense
They are waiting to be spoon fed the answer as per their normal modus operandi I expect. 👍
People, people, people. The guys in the safety vests with the trucks are the engineers, environmental folks etc. They specified the sizing and shape of the trench. Give the excavator operator a break. He is simply meeting the specifications......
Every other country uses a boogie board, a convenience store shovel and gravity for the project.
No hard hats, just a lot of excitement as the sides of the sand are cleaved away by the ever increasing flow
I grew up near Glenrock Lagoon in NSW. The lagoon cyclically fills, washes open across the beach, builds the sand back up and repeat. It seems odd that this one doesn't open by itself.
It does, I went fishing down here years ago and the winter rains used to break through it maybe they’ve had a bad year rain wise. But regardless, this should be left to nature to sort out because these cycles are normal. The snapper grow up in there and when it breaks they are met by the sharks on the other side, meanwhile it’s great fishing before this happens.
It does open by itself, but the level in which it would naturally open up would flood too much land upstream so they open it up earlier.
At what point in the video are the kayak races?
Some explanation would be useful. Presumably the freshwater lake is fed by a river which eventually will be surrounded by mud flats when fully drained. Will this provide a wildlife habitat or is this an engineering solution to free up an area for future land use?
There is information in the description.
@@currysues Not much
Yes, the Denmark River and other streams flow into the Wilson Inlet. Flow is dependent on rainfall alone, and this is mainly in winter. Good rainfall is required to breach the bar. The road and low-lying areas around the estuary/inlet would flood if the bar was left to breach naturally. When levels have dropped the sand bar rebuilds to several meters above sea level, closing it off from the ocean. This can take days to several months.
Seriously...read the video description. Want more info? Google.
They wouldn't be doing this if it didn't GREATLY benefit them in some way
Музыкальный ряд - потрясающий ! Спасибо ...
"Hey, could you get a few drone shots for this dig?"
OP: I got you covered fam.
Shoreface948 Its an amazing video and the excavator did a very professional job. I enjoyed watching very much. I would however like to know the purpose of joining the estuary and the sea like they did. It would complete the story for me, Thanks 😊
When the lagoon backs up with water especially flood waters in winter...
it destroys valuable land etc further back upstream...
and we can't have that mate...
we pay rates...
dig that channel!
Watch the boom in shellfish numbers with all that sediment feeding them.
Is that a double bass being bowed? Definitely a great foundation for the piece. Mucho gusto!
Great video, I love Denmark and Albany areas. Denmark won Town of the Year many times too.
Lovely job on the video. Beautifully lit and such great scenery.
Why did you dig four times the trench you needed?
because the excavator was rented and the operator payed full up front, so they said "make it 2 shovels wide!"
Maybe you tell those guys with the degrees and the experience of doing it on a semi-annual basis. I'm sure they'll realize the error of their ways and hold digapalooza next year. A few man buns with beach toys and it'll be open in mere minutes. There's no way that a 25 ton machine can beat some groms with sand toys.
It quarters the risk of the sea being naughty and closing it back up again...?.
@@JohnSmith-pl2bkdu brauchst im Prinzip nur einen ganz kleinen Graben, durch die Strömung vom Wasser wird immer mehr und mehr Sand mitgerissen und wird von allein zum Fluss... Da verstopft nix wenn der Graben erst einmal fließen kann😅
Die Leute aus dem Video haben als Kinder nie im Sand am Meer oder Badesee gespielt und Gräben mit Wasser frei gespült 🤷♀️
@@kleinerstubentiger
The sandbar didn't just materialise...the strong wave action caused it to accumulate...and a small ditch might have been overcome by the wave action before achieving a full scoring flow of water.
They do this every year. have done for 100 years.
I bet they know what they are dong...
Awesome video! Makes me want to visit!
Awesome shots !! I love how creative the drone shots were are able to create. It’s an amazing tool for creating!! And the pilot has the ability to create their own vision into reality!! Subbed my friend!
Favorite word is „create“, thanks for sharing this.
But was there any standing wave action????
It was a cool video. I look forward to seeing you get better. ❤
They make it double wide so the sides don’t crowd the excavator. They’ve been doing this every year for over 100 years, trust that they know what they’re doing.
and here, I was thinking man that's a nice beach in Danmark 😂.
Before digging the plug, it kinda reminds me of the Suez Canal from Goggle Earth. I imagined them putting in miniature locks on it. Row boats and swan paddle boats paying 50 cents to pass through each lock on the "canal". LOL I don't know where my mind goes sometimes...apparently some hydrological Mr. Rodgers Neighborhood.
HA! Looks like the operator was in his own world too. He built as much tension as he could dragging out the last few buckets. Maybe the operator was thinking "And Moses stretched forth his hand over the sea, and the sea returned...".
The Ayatollah of Rock and Rollah makes a good point.
The only reason they should have that many engineers is to make a permanent lock system to do this each year.
As far as I can see, the excavator driver is taking a simple job and fleshing it out into two days work for very little reason. The sediment all appears fine and mobile, and the water level in the estuary is higher than the ocean. So all you actually need to do is to make a trench about a foot wide through the sand bank blocking the bay where the bottom of the trench is just below estuary water level and the water flow will then do everything else for you once you breach the sandbank.
Of course this is a mere half day of work on a mini-digger and the operator doesn't get to make a completely unnecessary freshwater trench and also doesn't get to put in a nice curve and all that stuff (which disappeared as water eroded it) so his enjoyment is likely diminished, but it does save you a fair amount of machine time.
I was thinking something similar. Bring in a D-7 CAT bulldozer and just clear a line from the estuary to the ocean till it's lower than the estuary, then let nature take it's course.
He's just digging the size and shape of trench he's been instructed to. Sheesh, you armchair experts have got the poor bloke tarred and feathered and you haven't even raised a sweat!
@@SafeTrucking No, not the operator, the bosses that hired him. Yeah, he's just doing his job. But the designers of the project are the ones that appear not to have really thought this thing through. Lots of simpler ways to get it done. For instance, they didn't really need a plug between the estuary and the channel. Just keep digging the channel with the water in it. At some point, it will be lower than the estuary and nature will take over. No need to dig all the way to the ocean like they did.
@@Woody615 I'd say they've thought it through pretty extensively, but I don't care enough to get worked up about it. It was a nice vid to watch. :)
@@SafeTrucking True. Agree. Have a good one.
Beautiful. The river got to the sea. Living inland this reminds of how much I miss the ocean. Thankyou.
Come on everyone, who wouldn't love to play in a big sand pit with a real Tonka tuff digger like that.
Im surprised he didn't stretch it out to a week.😂
Denmark?!
Isn't this on the South West of Australia?
Yes to both. There is a town called Denmark just north of the inlet.
I can't dig around a little in a creek in my state because "it would disrupt the ecology." Australia:
Rich people affected.
Maybe because they know what they’re doing?
Qld you can
Because letting one person do it is fine, letting everyone do it leads to cholera.
Before they did that dig they 100% did a extensive repot of why its neeeded, tidal range energy input can help ecosystems alot. The brown water is i assume cus of the lack of oxygen.
What's the point of the digging?
The reason for it is unchanged since it was originally written in the description under the title.
👓👓👓
@@Salutimondo They are digging because their old uncle won't sign the bill of sale?
Sounds like you need the same solution used at the "Lake Illawarra" entrance. It's now permanently open.
Digging it out once a year is way cheaper.
Superb, well Filmed.
So how did the planet manage before humans came along and invented excavators and fluorescent jackets?
The planet managed by flooding the area where people have now built buildings and roads, until the flooding breached the sand bar itself. In other words this is a man-made problem.
@@-Gorby- actualy not. The riverbed continues in the sea. And it was all-year draining until 6000 years ago when Aboriginal Australians decided to close it for fishing in the winter.
Even today after the water drops it remains small channel that humans close on pourpose every year. This raises the lake very slowly during the non-rainy season year and it breaches(usually by itself) however it does not close by itself.
@@Xizario2 So, I am still right though - this is a man-made problem.
Interesting vid. Thanks for sharing.
No reason to have the initial channel be so wide deep or long
better than asmr
RIP to that machine. I'm sure it ended up at auction within a month of this job covered in rust
_One very careful lady owner, always garaged, dry weekend use only - never raced or rallied_
Washed in freshwater and sprayed down with a diesel/oil spray...all good.
Why can't they put in a culvert or a cement river .?
If they're doing this every year I would have to guess that the ocean is putting all that sand back with the tides. Cuvert wouldn't work because of this
They should use the left over sand for dunes
Hi, @cameroonkendrick6312.
And just where would they/you build these dunes so that they
a. would not wash or blow back into the bar area?
b. would not destroy any existing landscape or environment?
c. would not interfere with recreational access to the area?
A 'kew-ree-yuss' mind would like to know.
Just my 0.02.
You have a wonderful day. Best wishes. Deas Plant.
Okay, so exactly why does this inlet silt up like this? Is it a heavy sand load of the river? Or do currents force the sand to pile up? Why does it close that way?
Yes....
google is your friend....
Long shore drift forces sand to build up into a sand bar which blocks it every year.
@@JohnSmith-pl2bkCan stand comments like this. Someone is genuinely curious about the video and wants to hear from likeminded people and some dumb-arse in the comments is like “just look it up yourself 🤡”.
Or instead of wasting money on a dozen public works people sitting around twiddling their thumbs and an excavator, put out an announcement that the beach is ready to be breached and get some food trucks on the beach, make it a party and people from all over would come to dig it out for free.
In California kids would have done it to ride the outlet just on casual mention they wouldn’t be jailed
They do this in Hawaii and surf the channel
I think they are there for safety. Worse case scenario kind of thing lots could go wrong
Best idea!
And/or get the prisoners from the jail, and say, ok, here is your "community service project." Start digging.
Legend says it slows down the rotation of the earth by .00001 seconds on that day!
The number of vehicles on the beach indicates the Mongolian-Hordes approach to the job.
1 worker in the digger,
4 geologists,
2 Marine environmentalists,
two surveyors
and one poor sap to put in poles to do with elf and safety to keep the crowds away...
Hey, is that one dude in the light blue or grey jacket and brown pants playing the bagpipes?
Thanks for helping the estuary, without connection to the ocean, it’s an unatural lake.
Cool. What's the point of digging a channel?
Actually this is a common phenomenon...it's completely natural. The tides silt up the river mouth naturally and when either a storm breaks the dike or the water behind it over-tops the bar it flushes itself out. As soon as the water is low enough, it will silt itself up again and start all over again.
@@pastorjerrykliner3162 Except where I live, they diverted the river for a railway, slowing its flow and preventing scouring. So the valley floods - but they've just spent millions on a new bridge to span the flood that has been delayed because the valley floods making bridge construction difficult !
Why did they dig the initial channel so diagonally? It was orobably 3 or 4 times longer than needed to be. Then nature takes over and says.... yes, straight line please.
I pretty sure there’s a reason for it. For instance, the diagonal cut might eventually result in a wider breach which will make the flow faster.
Goddamn music. Why?
cool video but you didnt show the tide come back in
Holy crapoly... I live in Denmark and havent noticed that... OOh wait.. it is another Denmark.. aah, sorry, what a releaf... 😉🤗🙄
I was thinking the same!
I haven't been to Denmark the country,but I have been here and it's an amazing place and I can only guess someone who knew of Denmark before named it.

Am I correct in assuming that the water is black/dark like that is because of all the organic material decomposing in the saltwater also no circulation and movement of water flow.
Tannins in water I believe so yes you're correct
Excavator must getting paid by the hour
So if there is strong storm.. those area will flooded more than before because of no no barrier?
The storm when it washes up the beach deposits sand and blocks the hole in the beach....so the barrier reforms...
Good on you for flying your drone where you probably wouldn't get it back if it crashed.
P4 Pro was very reliable, and it was a VLOS operation. However, with time in the salty environment the systems did become less reliable.
Kinda makes it look like the sea levels are dropping, not rising. Whats with the diagonal trench? Waste of fuel and time compared with a more direct trench.
Armchair expert alert....
Nice report thanks 🙏

Why dont they dig the most direct route
The diagonal protects the trench until the trench digs itself deep enough and wide enough to prevent the waves from stopping it up again.....
When it gets really strong and wide outflows it obviously straightens up...
it's big enough then to do what it wants and can't be overpowered by the waves.
Am I the only one that sees this as inefficient? Three bulldozers working at gaps of several hundred metres just pushing the soil across in to a pile would be far faster than a single digger swinging back and forth?
Inefficient ? Unless there is a good reason like a emergency of sorts. The extra cost would be 2 times more or you could just speed YT by 2x.

I've only been to that area a few times and it was a long time ago. I had no idea that this was done, never mind every year! Most interesting.
A waste of energy, a one foot wide trench had been enough, auto-enlarging with the flow created.
I think that doesn't work when the channel is long
@@cakestationary8044 Ah ok you maybe right ty
Agreed, a thin direct trench to get the water started was all that was needed. Gravity would rapidly do the rest.
