Fluvial System Block Diagrams
--
I was looking to understand a fluvial system the other day, up in the high Arctic, as I looked at 3DEP remote sensed elevation data… I have always been fascinated by the how geology, water, weather shapes a landscape, including erosion (aka geomorphology if you will) – and realized how very much value fluvial block diagrams have as we try to conceptualise what has, is and will happen(ed.)

@fff the funny thing is : there was a year long study if its possible to find markers for the Anthropozän
you, he - we all - may watch this : youtube.com/watch?v=v1M5dDuh1V

which (only) prooves that humans leave many distinct and significant marks in earth climate and geological processes.

TL;DR too much sand!

Also, the 9-foot channel depth has done a lot of damage to the ecosystems of the Mississippi.

"Since Congress required the 9-foot shipping channel in 1930, that navigation mission remains first & foremost for the Corps on the river. ...under natural conditions, the upper Mississippi River was 2 feet deep or shallower during low water."
