Water area (Water Overlay)
Revision as of 08:17, 13 June 2019 by Rudolf@tygron.nl (talk | contribs)
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.
If no water level areas are present, no water is initialized in the water terrains. Waterways and other water bodies will be dry at the start of the simulation (unless an inundation area is present, which performs a similar function).
If the underground model is active, and no groundwater GeoTiff is present, the watertable is initialized at the height defined by the water level area.

Notes
- A water level area represents real-world water level areas.
- 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 level might not suffice, since the level is a datum height, not a relative offset from the bottom.
