Building a Water Resources Foundation

Water resource managers use GIS technology to visualize and analyze topographic, hydrographic, and hydrologic data for tasks such as assessing water quality, estimating water availability, planning flood prevention, understanding the natural environment, and managing water resources.

Esri's Arc Hydro consists of a data model, toolset, and workflows developed over the years to support specific GIS implementations in water resources. It operates on both ArcGIS 10.x and ArcGIS Pro platforms. Arc Hydro helps you build a foundational dataset that can be used in water resources analyses and for integration with water resource models. It standardizes water data structures so that data can be used consistently and efficiently to solve water resource problems at any spatial scale.
