Project Type: Specific Cooperative Agreement

Start Date: Sep 16, 2008
End Date: Jun 30, 2010

Objective:
1. Identify and evaluate existing methodologies for using high-resolution DEMs to calculate slope length and steepness, as well as determine the most appropriate aggregation of soil loss calculations across a field landscape. 2. Optimize the current RUSLE2 application to handle multiple calculations.

Approach:
Prepare a report on most appropriate methodology for using DEMs to interact with RUSLE2 and most appropriate application of RUSLE2 soil loss calculation across a field landscape. Document functional requirements for a GIS-based tool for statewide application. Evaluate slope length and steepness algorithms for applying LiDAR-derived DEMs to RUSLE2 model.
