Terrain modeling and Soil Erosion Simulations for Fort Hood and Fort Polk
test areas

rast=name raster input file
vect=name vector input file containing stream
output=name raster output file
[points=name] vector output file for adjusted stream points
[width=value] width of streams (in meters)
[depth=value] additional depth
-q quiet - do not show progress
-n no flat areas allowed in flow direction
r.carve does not create a depressionless DEM because many depressions are in
flat areas and not in the streams.

The program will take the vector stream data, transform them to raster, and
subtracts a defaultdepth + additionaldepth from the DEM. If the given
width is more than 1 cell it will carve the stream with the given width.
With -n option it should eliminate all flat cells within the stream, so
when and if the water gets into the stream it will flow. Vector
('points') option generates x,y,z for points which define the stream
with the z value of the bottom of the carved-in stream. These points
can then be combined with contour points to interpolate a new DEM with
better representation of valleys.
It has not been thoroughly tested so not all option may work properly -
but this was the intention.
