Understand flooding using ArcGIS Pro with new flood simulation workflows, Arc Hydro and the Flood Impact Analysis solution
Summary
After defining a flood scenario for an area of interest, you would be able to do the following: • Identify how added rainfall, water source points, and initial depth interact with the terrain • Determine how barriers and channels could redirect flow • Visualize how water is removed by infiltration and evaporation This tool runs directly upon the content being drawn in the 3D view and is particularly useful for geodesign scenarios in which you need to try out multiple ideas quickly. It is not meant to replace existing engineering-style flood simulation models, but rather to help users get reasonable estimates quickly and iteratively, and then focus more deeply on an area. With flood simulation, you can then focus on these hot spot areas to test various mitigation measures, such as placing berms to divert water flow away from a section of buildings. The flexibility of flood simulation being able to run multiple scenarios to test and see the effects of implementing various mitigation measures also means users can see what yields the least impact—invaluable knowledge when you need to act quickly in an emergency. ArcGIS Pro has comprehensive workflows that support communities looking to understand flooding: • Arc Hydro completes complex analysis at all scales in 2D.
