What if you laid out all the meanders of a river along a straight line, so that you can break the river into straight-ish segments and fill arbitrary spaces? This is the Purus River in Brazil; you can see how it is getting wider and the meanders are getting larger in the downstream direction

Landscape evolution modeling with Landlab in my 300-level geomorph class this week. I like to add a heavy dose of fluvial erosion at the end so it turns into a Loess Plateau/Loess Canyons of Nebraska kind of landscape. I can't say enough good things about Landlab and the people who developed it

Relative elevation model of Powder River near Broadus, Montana. So fun to see the floodplain features pop with a bit of color!

Using reconstructed images, we create synthetic stratigraphy for the Ucayali River based on estimated aggradation and channel preservation rates. Though not fully realistic, it might be helpful for comparing with field data. Spot the two 5m-tall (unrealistic for sure) geologists for scale? :)

Image warping offers powerful solutions for reconstructing landscape evolution, even with incomplete satellite data. Check out these examples: from simple head-turning motions in cats to detailed reconstructions of the Ucayali River and Wax Lake Delta, all using just two input images!
