A Template Data Model for Water Resources
Developed by leaders from industry, government, and
academia, Arc Hydro is a GIS data structure that links
hydrologic data to water resource modeling and decisionmaking
methods. Using Arc Hydro helps you build a dataset
that can be integrated with water resource models. The
Arc Hydro data model standardizes water data structures
so that data can be used consistently and ef ciently to
solve water resource problems at any spatial scale. It gives
you a starting point for building your own data model and
integrates with the Arc Hydro tools.
