PrefaceThe ArcGIS Hydro Data Model is one of a series of GeoDatabase models, which theEnvironmental Systems Research Institute (ESRI) is developing in collaboration withpartners. Each GeoDatabase model is described in a book, at the back of which is a CD-ROM containing the model structure, and GeoDatabases for example applications of themodel. A GeoDatabase model is a framework for capturing key geographic anddescriptive information about a class of landscape features, and for attaching behaviors tothe features. The GeoDatabase is accessed using ESRI’s new ArcInfo version 8software, in which objects interact through interfaces designed according a commonstandard.The ArcGIS Hydro Data Model was developed through a collaboration between ESRIand the Center for Research in Water Resources (CRWR) of the University of Texas atAustin. Together, ESRI and CRWR formed a Consortium for GIS in Water Resourcesto bring together industry, government and academic partners in a joint effort to build adata model for surface water hydrology and hydrography. The collaborative effort wasmounted through a series of meetings, a GIS in Water Resources Conference, andsubstantial interaction through the internet, to arrive at the data model structure describedin this book. No single individual could have conceived the whole model its structureis a synthesis of knowledge of the water resources area and of the capabilities of theArcInfo software, designed to operate efficiently within those capabilities.This manuscript and the accompanying CD-ROM were prepared for the GIS Hydro 2000PreConference Seminar held at the ESRI User Conference in San Diego in June 2000.Both the manuscript and the data model are draft versions intended for review by the GISin Water Resources community. Comments and suggestions as to how the manuscriptand model can be improved are welcome and solicited. After the model and manuscriptreview are completed, and appropriate adjustments made to their content, the ArcGISData Model and accompanying book will be published by ESRI Press.We wish to acknowledge the generous collaboration and support, which this effort hasreceived from the water resources community. In particular, the following organizationshave financially supported research efforts of the Consortium for GIS in WaterResources: ESRI, US Environmental Protection Agency, Texas Natural ResourcesConservation Commission, Lower Colorado River Authority, City of Austin, Texas,Dodson and Associates, Camp, Dresser and McKee, and the DHI Institute for Waterand Environment.Individuals from many other organizations also contributed information and suggestions.In particular we wish to acknowledge the contribution of the National HydrographyDataset program of the USGS and EPA whose development of a hydrographic datamodel for the United States was a significant guide to this effort. We thank all thosewhose ideas and support have contributed to the ArcGIS Data Model.
