Introduction to Flood Impact Analysis

Flood Impact Analysis can be used to develop localized flooding scenarios and visualize the impact of flooding on public infrastructure, critical facilities, and vulnerable populations.

The solution allows you to understand and visualize the impact of flooding on the community by using flood depth and elevation data to analyze the impact of river flooding, storm surge, tidal surge, and sea level rise scenarios. The results of the analysis can be used to plan road closures, prioritize evacuation areas, and develop mitigation strategies. Flood Impact Analysis is typically implemented by emergency management, public works, and planning organizations that want to prepare for future flooding to protect their communities.

The Flood Impact Analysis solution allows you to prepare flood depth and elevation data, define flood impact areas, visualize the flood in 3D, and share the information with the public or other organizations.

Deploy the solution

This ArcGIS solution can be deployed in your ArcGIS organization.

See Deploy an ArcGIS solution for more information.

Requirements

The Flood Impact Analysis solution requires the following:

Information products

Flood Impact Analysis includes the following information products:

Item	Description	Minimum User Type
FloodImpactAnalysis.ppkx	An ArcGIS Pro project package used by mapping technicians to create flood impact maps	GIS Professional Advanced

When you deploy this solution in your ArcGIS organization, you also get an ArcGIS solution item that organizes the key information products and summarizes all the ArcGIS items (applications, forms, projects, maps, feature layers, feature layer views, and so on) included with the solution. The ArcGIS solution item also illustrates any dependencies items have on each other.

Release notes

The following are the release notes:
