Topographic analysis and potential for erosion and deposition for test data

Helena Mitasova, Lubos Mitas
University of Illinois at Urbana-Champaign

PRELIMINARY RESULTS

old elevation data

DEM (10m resolution) computed from 5m contours by s.surf.rst:

elevation
slope
aspect
profile curvature
contour curvature

Results from USPED for the entire installation at 10m resolution:

upslope area (steady state water flow)
detachment limited erosion potential for uniform cover
net erosion/deposition (transport capacity limited case for uniform cover
detachment limited erosion potential for cover in 1989

Multiscale representation of water flow in eastern part watershed (in this image each scale is done independently, so water does not flow from one to another, multiscale simulation will be able to do it properly)
upslope area
upslope area with 5m contours and streams
note that the stream data do not fit perfectly with contours, see my email
