We would like to get the names and addresses of people who
are using GRASS and DEM data to generate a stream drainage
network and the derivative quantitative geomorphic
parameters (Horton-Strahler or better). That is, who has used
GRASS to get stream orders, and number, length, slope,
drainage area, etc., per order? We know of this having been
done with ARC-INFO, and we know of Garbrecht's generation
of these data with Fortran, but who has done it with GRASS
only?
I am doing an hydrologic/erosion modelling project with ANSWERS, a grid
based model. Values of slope aspect etc were read in from a DTM package
TAPESG. I have also used other attributes (profile curvature, plan
curvature, contributing area etc) from TAPESG in GRASS to do a classification
of crests, footslopes etc of the catchment.I am interested in what experiences
anyone has had in doing this type of classification.
