Calculating Secondary Port Tide Times and Heights
HTML-код
- Опубликовано: 13 июл 2024
- I calculate tide times and heights for the fictional secondary port named Edenfield.
Edenfield's standard port is Hamilton Sound. So I need to use the tidal information and curve for Hamilton sound, but calculate the differences for Edenfield first and then I can use the HW time, height and LW height on the Hamilton Sound tidal curve.
0:00 Describe problem scenario
1:24 Get tide times and heights from Almanac
1:50 Note particular HW and LW times and heights for date
2:25 Show Secondary Port differences from Almanac
2:45 Draw scale for Standard and Secondary port HW time differences
3:45 Calculate Secondary port HW time
3:53 Draw scale and calculate HW Height for Secondary port
5:48 Create Tidal Curve using HW Time and Height and LW height
7:18 Convert UTC-1 to local time
7:58 Calculate a second example for another day
8:45 Work out HW Time difference
9:07 Work out HW Height difference
9:22 Work out LW Height difference
9:27 Mark up Tidal curve using calculated data

The best video I’ve found so far regarding secondary ports. Very clear and simple and good to learn a method that isn’t ‘crocodile jaw’
been looking for the manual calculation one cuz i need to present it but man it's so confusing.. maybe i'll just present this method instead
you made the interpolation very easy.So far the best method I've ever come across.Thanks a bunch !!
Sir do you also need to take into account the seasonal changes?
No, I'm using the tide height values straight from the almanac for the particular date and time I'll be there.
@@sbcode thank you sir😁
@@sbcode Could you please explain this in more detail as why the seasonal correction is not required.Can we use the same method for Pacific tides as well.Thanks
The values from the almanac are seasonally corrected already. For Pacific almanacs you need to check with the publisher
low water was at 1613 not 1413
Well spotted. You are correct.
