Data Model User Group

Join the data model user group if you are an existing ArcGIS customer and want to learn more about design and architecture of personal or enterprise Geodatabase and become a part of ESRI’s growing data model community.

We invite user group members to participate in a series of instructional web casts. Please fill out the data model survey to give us feedback on what web casts you would like to see.

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.

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. To see a nationally recognized application and advancement of the ArcHydro data model visit PBS&J.
