Interpretive Summary: DotAGWA is an Internet based application that combines geospatial data and surface water models. Using a web browser like Internet Explorer©, end-users delineate a watershed and define a management plan for the watershed by drawing points, lines and/or polygons on a map. After defining the management plan the user can then create input data sets for one or more surface water simulations. The input data are gathered from various databases built into the application or accessible through the Internet. The input data sets are extracted by using the delineated watershed and once created are passed to the surface water models. Users then run the model(s) and are allowed to download the output data for further analysis and/or review. All of the features built into the web application are hosted on a server that making the application available to anyone with a computer and an Internet connection

Technical Abstract: DotAGWA is a shared application used to assist watershed planners in decision making processes and to offset the software and data requirements typically required in a desktop application. The features available in DotAGWA help planners share and visualize data. Groups can interact with the application to help facilitate the communication and decision making processes. Planners access the application through an Internet browser interface. Application servers connect the user-interface to the database servers (both spatial and non-spatial). The application servers also connect the user and the data to the hydrologic models. Users can define management scenarios, attach models to a plan and have the application parameterize and run the models for the defined management plan. The user can specify different output formats (i.e., XML, Word doc, HTML) for the resulting simulation output. Finally, the DotAGWA architecture provides access to some of the sub-components of the application. The sub-components can be used by other people or applications further extending the use of the overall application.
