Shoreline (Water Overlay)

Icon	Attribute	Unit	Range	Description	Default value
	SHORELINE	boolean		Whether to automatically fill cells near a water terrain when there is a mismatch between the extend of the water terrain and the DEM.	n/a

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.
