I'm member of the "Arbeitsgruppe Computergestuetzte Geomorphologie" 
(workinggroup computer aided geomorphology), Department of Geography, Univ.
Heidelberg (Germany), working together with Dr. R. Dikau.

There are several subjects we are handling with:

- regionalization in Hydrology
- soil erosion
- natural hazard assessment
- landform classification
- landform - soil relationships
- general morphometry 

Since the last ten years this group developed some tools, concernig computer 
aided geomorphology. For example a landform modeling tool, that deliniates
30 morphometric attributes from DEM's, including cummulative upslope catchment
calculation with a divergent flow algorithm. Currently, we are testing some of these 
tools ported to GRASS. 

I agree to summarize these responses. Besides that I think, that we 
(quantitative geomorphologists) should keep closer contact. 
In general, we are very interested in exchanging data and models.

Dear Richard Beechman,

please contact me or better Dr. Dikau (rdikau at geo0.geog.uni-heidelberg.de), 
concerning landform classification.
