Desert Pavement Studies

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.
