This website has been designed by the Center for Research in Water Resources (CRWR) as a complementary source of support to the already existing documents, websites, and reports available online about the GIS Data Model for Water Resources, Arc Hydro.

Through this page you can find information that will help you successfully generate an Arc Hydro Data Model for your case-specific project based on your own needs and data availability. Thus, the main contribution of this page is to guide you through the process of managing and manipulating your spatial datasets to comply with the Arc Hydro Data Model design.

From the table of content, you will find a list of links for relevant issues on the Arc Hydro Data Model. The main contributions to your Data Model generation are located under the "Model Implementation" topic. That Link contains a series of guidelines and suggestions on the step-by-step process that is necessary to carry on in order to format your data with the standards of the model and to readily enhance your spatial project with all the features and functionality that the Arc Hydro Data Model delivers.
