When a Waterway polygon is not correctly positioned in relation to the DEM this can result in filling up the nearby land with water at the start of the simulation. This will result in a lower water level then is expected from the water area value. To correct this, a "shoreline" is added at neighbouring cells. At the start of the simulation, these shoreline cells will also be filled with water up to the nearby water level to prevent the initial flush.
notes
- With value 0 no neighboring cells will be added to the shoreline.
- With value 1 direct neighboring cells will be added to the shoreline.
- With value 2 direct and diagonal neighboring cells will be added to the shoreline.
-
Water Overlay with shoreline active. -
Water Overlay without shoreline active. -
Difference in water level.
Notes
- This option is active by default.
- Shoreline currently only extends to one grid cell in each direction, as can be seen in the images above.
