    This really reminds me of some things I saw on a recent trip to Washington. I climbed Mt. St. Helens there, and from the Crater Rim, you could see the North Fork Toutle, still carved, scarred and littered with debris and dead trees. The size of this debris flow is not quite as big as some lahars get, but some of the videos from the St. Helens lahars really give a good picture of what debris flows like this look like.

    Interesting video, I live in Watauga across the street from one of the large landslides in our area. It took out our power lines, crews are still working so people have access to their homes. The road was under 12 feet of mud, rock, and trees. Spoke to the farmer that saw it come down. His rain gauge was at 24” for the day before it rolled down around 11am, sounded like a freight train.

    I have to wonder if, during the early hours of Helene’s extreme rainfall, smaller, up-slope debris-flows might have dammed the creeks and impounded water. Then, that debris dam would burst, releasing the original debris, but with a torrent of impounded water pushing it down the valleys. (Here in mountainous Albemarle County, Virginia, in its southern half, and more-so in neighboring Nelson County, the high-up mountain-scars from the 1969 Camille Disaster are still visible….mostly rock, the finer debris long eroded.)

  • @wohnai
    @wohnai 2 часа назад +7

    One thing that seems to be lost in the debris flow discussion is every ridge and drainage area continued to feed additional water even if it didn't cause additional debris flows it's still adding flood water and minor debris. Is this a significant factor in the length of the major flows?

Look at the Tye River Valley today and the slopes of the Priest Mountain and Three Ridges.

All of them. Miles and miles and miles of trees just gone. When the grasses grow back on the banks, it’ll look like a giant version of a grass creek. With all the trees gone, is it going to make these kinds of areas along the river more prone to flooding?

    (and has closed the road since)
