A geographic information system for targeting nonpoint- source agricultural pollution

ABSTRACT: A computerized geographic information system is being developed for use with the universal soil loss equation and a delivery ratio to estimate potential sediment loading to streams from agricultural land. The potential sediment loading estimates will be used to target cost-share monies in Virginia9s Chesapeake Bay drainage basin. The computerized approach has been shown to be more effective and less expensive and to hold greater potential for reuse than manual methods.
