I have a (relatively) High resolution DSM of the Country side, and want to figure out the extent of area that will be flooded if the Embankment/levee fails at a a given point.
I'm trying to do some research on this, and I'm drawing a blank, mostly because I don't know what this is called. Without proper keywords, A Google Search is extremely fruitless.
What is this kind of Analysis called? Are there any standard Algorithms/Models for this?
Are there any freely available tools for doing this kind of Analysis?
