I am modeling several miles of the Des Moines River in central Iowa using DEM maps. This means that the river bed drops in height as it goes down stream. I have tried to create water in the riverbed, but if I make the water level high enough to cover the river bottom upsteam, downstream becomes flooded. I have tried making breaks in the water, installing it at different levels as I move downstream. When I go back upstream, the river is dry - all the water goes to the latest level created. I know I can have multiple levels because the lake several miles away and 250 ft higher is not affected by what happens on the river.
Any tips on putting water in a river?
