Rainfall Overlay

Rainfall overlay

The Rainfall Overlay is a variant of the Water Overlay, which in turn is an grid overlay based on the water module calculations that displays the hazard and impact of (heavy) rainfall over the project area. Based on the elevation model, terrain roughness and representations of the sewer and water systems, several result types can be displayed.

A Rainfall Overlay Tutorial is available to start working with this overlay.
