ArcHydro: GIS for Water Resources, the latest title from ESRI Press, describes how a water resources data model, ArcHydro, is being applied within geographic information system (GIS) technology to provide a wide variety of hydrologic solutions. Edited by David R. Maidment, the world’s leading authority on water resources and GIS, this book presents ArcHydro concepts, components, and applications, and it is now available for purchase.
ArcHydro was developed by leaders from industry, government, and academia as a data structure that links hydrologic data to water resource models and decision-making methods. Now water resource data can be described in a standardized way so that it can be consistently and easily used to solve water resource problems such as assessing water quality, determining water availability, preventing flooding, understanding the natural environment, and managing water resources on a local or regional scale. ArcHydro opens the way to building hydrologic information systems that synthesize geospatial and temporal water resource data to support hydrologic analysis and modeling. With this book and companion CD-ROM, users can create hydro networks of rivers and streams, link hydro networks to drainage areas, represent rivers as three-dimensional models, and connect water features to time series measurements recorded at gauging sites.
ESRI, the world’s leading provider of GIS software, initiated the development of the ArcHydro data model as part of its commitment to provide its user base in various industries with a template of standard data classifications and features that are immediately useful to end users. Using a data model promotes interoperability and sharing between organizations and water resource agencies using existing data, allowing these organizations to standardize their data. Organizations that have yet to develop data will find that the ArcHydro objects, features, and tools provide an easy to use method for getting started.
