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 (but explicitly not on water). Template:Overlay attribute

Notes

• 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. Alternatives, such as staggered inundation areas, or initializing the waterway dry, should be considered.
