ENVIRONMENTAL MODELING OF MISSOURI STREAMS USING HYDROLOGIC SIMULATION PROGRAM-FORTRAN (HSPF) PROJECT
The project location will cover the Goodwater Creek watershed in northern Boone and western Audrian Counties. The project will last from June 30, 1998 to July 1, 1999.
PROJECT DESCRIPTION
The HSPF will be applied to the Goodwater Creek watershed, located in northern Boone and western Audrain counties. This 28 square mile watershed has undergone extensive monitoring as part of the Missouri Management System Evaluation Area (MSEA) project. Rainfall has been observed using an array of recording raingauges and runoff measured on three nested watersheds since the early 1970's. Weekly grab samples have been tested for nitrogen for most of that time. A weather station has been used to record maximum and minimum temperatures and, during the growing season, pan evaporation.
The inception of the MSEA project led to adding three instrumented field-size watersheds to the project. Weirs were installed on each field for water measurement and automated samplers for pesticide, nutrient and sediment sampling. At the same time automated samplers were added to the three gauging sites on Goodwater Creek to get storm event runoff samples. The event sampling on Goodwater Creek was carried out at all three weir sites from the fall of 1992 through 1996. Starting in 1997, Goodwater Creek has only been sampled at the 28 sq. mi. outlet. The water samples collected have been analyzed for nutrients and herbicides, including atrazine concentration. Extensive land use surveys were made on the watershed for the years 1990 through 1993 for an earlier investigation using the SWAT model. The array of data available at the Goodwater Creek site makes it an excellent location for evaluation of the applicability of the HSPF computer model.
OBJECTIVES
Environmental Modeling of Missouri Streams Using HSPF -- The HSPF will be applied to the Goodwater Creek Watershed located in northern Boone and western Audrain counties. This study is to test the ability of the US Environmental Protection Agency's computer model, HSPF, to model water quality in streams draining agricultural watersheds in Missouri. The use of HSPF will be compared to an alternate computer model, SWAT, which has also been used for this purpose.
PRODUCTS
The final products from this project will be a report detailing the applicability of the HSPF model for use on Goodwater Creek. A set of data files developed for that watershed and some preliminary observations concerning application to other watersheds will be included.
