Abstract
A modeling system has been constructed around the Soil and Water Assessment Tool (SWAT) for the Upper Mississippi River Basin (UMRB), which covers over 491,000 km2 in parts of eight states in the north central U.S. The SWAT modeling system is designed to assess alternative management and/or land use scenarios, which have the potential to result in improved water quality within the UMRB and in the Gulf of Mexico. Key data sources for the modeling system include the U.S. Department of Agriculture (USDA) Natural Resources Inventory (NRI), the USDA Agricultural Resource Management Survey (ARMS), and Conservation Tillage Information Center (CTIC) tillage survey data. The development of SWAT UMRB baseline land use, crop rotation, tillage, fertilizer application, climate, and soil input data from these and other data sources will be described, as well as the process of generating hydrologic response units (HRUs) which are the basic spatial units required for a SWAT simulation. Issues related to differences between alternative data sources will also be discussed including: (1) differences in overall land use distributions reported in the NRI versus those available from U.S. Geological Survey (USGS) land use data, and (2) the distributions of conservation tillage reported between ARMS and CTIC.
