Hi
I want to work with r.plane and r.lake to get simulate floodings in DTMs.

In the section of interest there is a river which runs from about SSW to 
NNE. For r.plane I need the
azimuth. Is there a tool in GRASS which tells me the angle between two
points I mark on the map like I can measure in between two points with 
d.measure?



Could you recommend other tools to simulate  flooding events in GRASS?


Thank you
cheers
Philipp
