Introduction to Flood Impact Analysis

Flood Impact Analysis can be used to analyze the impact of flooding on critical infrastructure and share flood impact maps with internal and external stakeholders.

In recent years, the frequency and intensity of flooding disasters has increased and so has the impact on local communities. Over the last decade alone, floods have caused billions of dollars in property damage. As a result, local governments must be better prepared for flooding events so they can reduce the risk of property loss and protect human life.

When heavy rainfall or storm surges are predicted for a community, rich geospatial data (for example, flood depth, ground elevation, and public assets) and spatial analysis is used to analyze the impact of flooding and produce a series of flood impact maps. Flood impact maps communicate the extent of flooding events and provide valuable information about the affected areas and the potential risks and hazards to government officials and the public. They also help emergency management agencies develop mitigation strategies, plan road closures, and prioritize evacuation areas. Any delays in the production of flood impact maps could impact a community’s emergency response plans and reduce its resiliency to flooding events.

The Flood Impact Analysis solution delivers a set of capabilities that helps you develop localized flooding scenarios and visualize the impact of flooding on public infrastructure and critical facilities.

Deploy the solution

This ArcGIS solution can be deployed in your ArcGIS organization.

See Deploying a solution for more information.
