ESRI has developed models for Water Resources and has focused on surface water with input from key state, national, and international contributors. The ArcGIS Hydro model is available for review and download. We are also supporting a groundwater data model initiative and will eventually consider the full hydrologic cycle as part of the Hydro effort.
ArcHydro Training Classes!
The instructor-led training classes provide an introduction to the Arc Hydro data model and associated software tools supporting hydrologic and hydraulic analysis with GIS. Two courses; ArcHydro GIS for Water Resources, and Hydrologic and Hydraulic Analysis can be found by searching the ESRI Instructor-Led Training site.
If you are interested in downloading the most recent version of the ArcHydro tools please contact ArcHydro.
For more information on the Water Resources data models please contact the Water Resources Consortium. This site is hosted by the Center for Research in Water Resources (CRWR) of the University of Texas at Austin.

Downloads - Tools
These tools have been developed together with the data models to provide new ways to leverage each industry specific model. They are designed to work with the data model templates and case studies, and can be used with the model, or with other data sets. These tools can be found on ArcScripts, and are not supported Esri software.

User Community
Oakland county has completed a version of their Hydrography data model that includes design concepts from ESRI's ArcHydro data model and the National Hydrography Dataset (NHD) known as NHDinGEO. The model contains point, line, and polygon geometry as well as a geometric network and two relationship classes. Also included in the model are tables that manage unique IDs across the entire Hydrography dataset. These IDs are helpful when using the ESRI ArcHydro tools, which model hydrologic flow for water resource management. The model can be found at the Oakland County Hydrography Model Website.
For more information on the Hydro Data Model check out the Arc Hydro Book.
