hello GRASSers,

I want to determine the temporary flooded area of a river (meadow). Based on
a streamchannel layer generated by r.watershed from a DEM I want to seperate
regions, whose elevations are a defined ammount higher than the raster cells
of the streamchannel layer. 
Is it principal possible to do this with r.mapcalc or is there a more simple
way to solve my problem...

thanks for enlightenment
