Abstract:

Erosion of farmlands due to concentrate flow is very severe on many unprotected fields across the county. Small channels can you in large gullies of not controlled. These small channels are routinely obliterated by tillage of the field and other routine farm operations only to be formed again. Since the 1960's the Universal Soil Loss Equation (USLE) has been used to estimate rill and sheet erosion. A model and computer program called Ephemeral Gully Erosion Estimate was developed by ARS. This paper describes the development of the EGEM which is a modification EGEE computer to meet SCS user needs.
