Inundation area (Water Overlay)
An inundation area is an initial placement of a quantity of water. This differs from the water level areas in that an inundation level allows you to place water anywhere on the surface.
|INUNDATION_LEVEL||m + datum||The height of the water on non-water surface terrains.||n/a|
- If a grid cell is not covered by an inundation area or it is marked as water, the grid cell will not be inundated.
- For terrain with a steep decline, using a single inundation area to define the inundation level might not suffice, since the level is a datum height, not a relative offset from the bottom.
