Data Model The Arc Hydro data model was developed to transition hydrologic modeling from an inventory-based data model to a behavioral model, established on the relationship between various hydrologic data sets. Arc Hydro has been adopted as the water resources industry standard geodatabase structure or “schema” and is comprised of five major data types: drainage features, geometric flow network, hydrography, channel description and time series. The relationships between the layers are determined by...
