Abstract:

Combining plan view information from aerial photography showing details of stream channels on desert pavement surfaces with process-based erosion models, a high-resolution, synthetic topography DEM with resolution similar to that of the photograph is constructed. This topographic information is used to route water to small channels usually unresolved on standard topographic maps on the pavement surface that support most of the vegetation. Estimates of water discharge in these channels are combined with field data to estimate quantitatively the response of vegetation to specified changes in infiltration, climate, or other causes of changes in runoff. A regional riparian response index is derived.
