Soil Erosion Modeling for Improved Conservation Planning: |

Summary
Spatially and temporally explicit predictive abilities are needed to prevent and mitigate land degradation, off-site damage, and unsafe military training environments caused by excessive erosion, deposition, and runoff. The U.S. Army Corps of Engineers, Engineering Research and Development Center, Construction Engineering Research Laboratory, in collaboration with instrumental research partners at the University of Illinois at Urbana-Champaign Geographic Modeling Systems Lab, has made considerable progress in developing predictive erosion/deposition modeling capabilities.
This report, "Using Soil Erosion Modeling for Improved Conservation Planning: A GIS-based Tutorial" is intended to provide a summary of important background information on soil erosion and deposition modeling, including: 1) a description of models, 2) appropriate modeling approaches for various problem types and scales, 3) issues of data for models, and 4) instructions for implementing the models within several widely used geographical information system software packages.
As a tutorial, it is assumed the reader is familiar with soil and erosion science, erosion management practices, and Geographic Information Systems (GIS). As a result, this document provides a comprehensive reference overview of procedures and methods, rather than step-by-step instruction. It provides numerous examples of the use of erosion/deposition modeling in general, and specifically applications of a a modified Revised Universal Soil Loss (RUSLE) method, and a Unit Stream Power Erosion and Deposition (USPED) method at various scales and complexity. Examples also are directed toward the application of erosion/deposition modeling in the design and evaluation of land management practices for conservation and rehabilitation.
