Arc Hydro Developments for the Lower Colorado River Basinby Daniel R. Obenour, M.S.E. and David R. Maidment, PhD. ABSTRACT The Arc Hydro data model, developed by the Center for Research in Water Resources (CRWR) at the University of Texas at Austin, is the preeminent method for storing and analyzing basic hydrologic data within the GIS environment. The purpose of this project is to utilize Arc Hydro concepts to develop methods for managing existing data and models for the Lower Colorado River Basin. To accomplish this, an Arc Hydro Framework data model was created using available hydrography data for the basin. Second, time series data were added to the model, and the model was then tested in a SQL-server environment. Third, an Interface Data Model (IDM) was developed to store the contents of an existing hydrologic simulation model of the basin. Finally, a method for generating and archiving flood maps and damage statistics was developed. This project has demonstrated that the Arc Hydro data model is an effective tool for storing hydrologic data within the GIS world, but with some limitations. The project has also demonstrated the need for and the effectiveness of new data models (IDMs) when trying to facilitate the information found in complex computational programs. Finally, this project emphasizes the importance of having standardized data models based on Arc Hydro concepts when creating GIS applications to aid in hydrologic modeling.
