Dear GRASS users, maybe someone of you has already worked with r.sim.water while considering dams as impermeable structures that retain water, i.e. create impoundments/reservoirs.
I am wondering how to best specify dams within r.sim.water: There is the parameter flow_control which is a raster map that indicates the permeability of the landscape. The manual mentions here a permeability ratio (0-1) and I guess this should be 0 for all cells that represent a dam and 1 for all other cells of the computational region?! But what about the elevation data then; Do I need to provide an elevation raster that includes the dam height or should this be the elevation as without dams? I'd like to know whether I need to provide a flow_control map or an elevation map that includes dams or both? I couldn't find any example of r.sim.water that uses the flow_control parameter so far... any ideas/experiences from your side? cheers, Johannes
