Arc Hydro is a geospatial data model and set of tools developed by Esri in collaboration with the Center for Research in Water Resources (CRWR) at the University of Texas at Austin. It operates as an extension to the ArcGIS platform, providing a robust framework for managing water resources data. The tools facilitate the derivation of hydrologic features from digital elevation models (DEMs), the management of time-series data, and the creation of watershed models. This report outlines the architecture, key functionalities, and strategic importance of Arc Hydro Tools in modern hydrological analysis.
