Document Type: Proceeding Paper

Part of: Sediment Transport Modeling

Abstract:

The U.S. Soil Conservation Service (SCS) in cooperation with the Agricultural Research Service (ARS) has developed a microcomputer program to provide estimates of the average annual material removed from a single ephemeral gully knowing selected watershed characteristics. The program is user-friendly and uses Help screens and function keys. Limited validation studies indicated that the Ephemeral Gully Erosion Model (EGEM) computer program provides reasonable estimates of the material removed from a single event. AT AA NR 7
