Technical Abstract: Water pollution potential of livestock operations includes impairment of bacteriological quality, depletion of dissolved oxygen, and increased nutrient enrichment. The successful planning of a beef ranch management system requires the ability to simulate the impact of cattle stock rates, forage production, and pasture management on the water resources. A Beef RAnch Decision Support System (BRADSS) has been developed as a tool for creating alternative pasture management plans and evaluating the effects of such plans on surface and ground water quality degradation. BRADSS utilizes a GIS-based interface to develop field-level management plans, run the FHANTM v2.0 water quality model, and analyze the results obtained by means of tabular reports, daily time-series graphs and thematic maps. It is designed to allow the user a site-specific investigation of the water quality impacts resulting from field management practices. BRADSS runs on SUN SPARC stations using the ARC/INFO GIS software.
