Not that anyone asked but looking at a.) the fact that Carpenter says that it’s clay being torn from the riverbank by the floodwaters of the White Gull and b.) The Hjulström Curve:

We can determine that the flow velocity of the White Gull River in TSV45 was approximately 150-300 cm/s.

What does this mean? Absolutely nothing, I’m going to be so honest. I just find this amusing

#the silt verses #tsv #there is an image ID on the graph that hopefully explains how to read it but I’m afraid I explained it poorly #I also misjudged the placement of the point where the slop of the erosion line changes #if anyone was wondering clay and silt erode at higher velocities because as grain size gets super small #the individual grains tend to stick together much more and then they act as larger grains #and you’ll notice that clay and silt basically never settle out #like they need a velocity of 0 to be deposited #essentially #so that clay is going to flow out to the ocean and it might spend YEARS in suspension until it eventually settles #wow just like fau— GUNSHOT #sorry I’m just thinking about how he too will end up out in the water column. probably #and eventually he’ll sink #or maybe not #maybe he’ll get caught on a boulder that’s deposited by the floodwater #cause hey if the flow velocity is THAT high it’s probably also transporting some massive boulders and depositing them further downstream #where the channel widens and the flow velocity lowers #does anyone want to talk to me about sediment. I’m normal I promise #I’m putting my geoscience degree to WORK over here <- degree is still in progress I am Not An Expert #I hope my professors are proud of me
