Description:
The Data Base Analyzer and Parameter Estizator (DBAPE) is an interactive computer progran that provides a link between two of EPA's development products--an environmental model and a data base. BAPE was created to encourage and support the use of the RUSTIC model, a newly developed program that simulates the transport of field-applied pesticides in the crop root zone, the unsaturated zone, and the saturated zone. DBAPE provides an efficient means to obtain soils and meteorologic data needed to run RUSTIC from a data base that contains information on more than 8ooo agricultural soils and 200 meteorological statiions located throughout the contiguouS United States. Soils-related RUSTIC but that can he obtained by using DBAPE includes percent organic matter, wilting point, field capacity, residual water content, saturated hydraulic conductivity, and values for the van Genuchten parameters for the soil-water characteristic function. Meteorological data that are not distributed with DBAPE because of their volume. BAPE, however, allows the user to identifg the weather stations near his/her study site. eteorological data far these stations can then be obtained from the EPA's Environmental Research Laboratory, Athens GA. BAPE has utility not only as a support program for RUSTIC, but also as a stand-alone environment for (1) exploring the data base, (2) clarifying the impact of data on modeled processes, (3) screening geographically based data to identify potential sites for model testing, and (4) developing guidance on alternative management strategies.
