Most agricultural water quality models are based on lumped parameterizations of spatial processes. The Root Zone Water Quality Model 2 Geographic Information System (RZWQM2-GIS) water quality tool has been developed to predict space-time planning scenarios across spatially variable agricultural landscapes. RZWQM2-GIS was developed under the Microsoft Visual Studio .NET 2010 environment using the Visual C++ language, and embeds GIS functionality and customization based on programming calls to required ArcGISTM 10 ArcObject classes. The tool runs under the ArcGIS 10 environment, and consists of a multi-functional system for agricultural production and water quality simulation modeling; and spatial data storage, analysis, and display. RZWQM2-GIS offers a spatial framework for integrating a complex, agricultural system water quality model (modified RZWQM2) with interaction between simulated land areas via overland flow for improved prediction of water quality over a wide range of agricultural management practices and surface processes. RZWQM2-GIS also provides the increased interface sophistication necessary for distributed hydrologic modeling.
