<br /> <br />SMALL WATERSHED MODELING <br />AND ASSESSMENT USING GIS <br /> <br />,''< <br /> <br />~. <br /> <br />by <br />F. Charles Bairdl <br />Woody Frossard' <br />Gary K. Westmoreland' <br /> <br />( <br />, <br /> <br />; <br /> <br />The presentation describes a five-year cooperative project between Tarrant County Water Control <br />and Improvement District No. 1 (TCWCID) and the USDA - Soil Conservation Service (SCS) <br />begun in October 1992. Tarrant County WCID #1 controls five major reservoirs supplying water <br />to Fort Worth and several other Metroplex communities and industries:. The methodology used in <br />the project is being proposed by several entities to meet requirements of Texas Senate Bill 818 <br />which requires river basin assessments of water quality. <br /> <br />f <br /> <br />~ <br />[ <br /> <br />The SCS Water Resource Assessment Team is utilizing the SWAT (Soil and Water Assessment <br />Tool) model developed by USDA-ARS, Temple, TX. Scientists with Texas Agricultural <br />Experiment Station (T AES) have developed the interface between the Geographic Information <br />System (GIS) databases and SWAT to provide required model inputs. Spatial databases are <br />generally being developed at scales of 1 :24,000 and include such layers as soils, land use, and <br />topography. <br /> <br />~': <br /> <br />{ <br />, <br />I. <br /> <br />'. <br />~ <br /> <br />Intent of the project is to assess water quality under current sLIld projected management <br />conditions. The projected conditions will include Best Management Practices (BMPs) to reduce <br />non-point source pollution. Point source water quality conditions will also be modeled, however, <br />emphasis is placed on identifying non-point sources and BMPs to reduce them. <br /> <br />The paper appears to relate to several possible topics in watershed management including: <br /> <br />GIS Applications - GIS is driving the input to the SWAT modd. <br /> <br />Unique water quality and water quantity modeling applications - The SWAT model was <br />developed under the HUMUS (Hydrologic Unit Model for the United States) project by <br />the national office of SCS to conduct national assessments under the Resources <br />Conservation Act (RCA). <br /> <br />Best Management Practices - The SWAT model will compare current management <br />conditions to projected conditions including Best Management Practices to assess water <br />quality issues. <br /> <br />F.
