Import feature class as inputs for Water Area in Flood Simulation

kntr — Thu, 27 Feb 2025 23:47:05 GMT

ArcGIS Pro 3.4 introduces the ability to add water area as inputs for flood simulation. However, this can only be done by digitizing the water areas. It would be better if we can import water area polygons such as rivers, which would provide more accurate vertices and also reduce time required to manually digitizing many many water areas.

Notice how the river polygon is digitized with few vertices which is inaccurate. Digitizing rivers in a 3D scene is very time consuming, especially when river feature classes are readily available for use as open data.

Hi!

Thanks for submitting the user idea, and great to see people using flood simulation.

For this particular use-case, we allow you to pull the geometry from a selected polygon during the creation process. If you select a single polygon feature first, you can use that feature to create the water source area element (the button is on the overlay window).

The workflow is one element at a time, so no current support for importing multiple polygons.

Hope this helps!

-Nathan.

Hi.

Why there is no same option for Barrier and Channel. In my case there are alot of walls needs to be used as barrier and it is very difficult to draw them in scene.
