Water area (Water Overlay)

A Water level area is a means to specify the initial water level for large sections of your project area. This initial water level is only applied to water terrains. The datum height of the water level is assumed to be equal within the water level area.

A water level area represents real-world water level areas.

Notes

• Grid cells are marked as water by an overlapping water terrain. If a grid cell is marked as water, but is not covered by a water level area, the grid cell will not contain water.
• For waterways with a steep decline, using a single water level area to define the water height might not suffice, since the height is a datum height, not a relative offset from the bottom.
