Avg terrain width m (Water Overlay)

Average terrain width can be configured in the Simulation Settings step, when the surface water mode set to Avg Terrain.

Icon	Attribute	Unit	Range	Description	Default value
	AVG_TERRAIN_WIDTH_M	m	0 to 10000 grid cells	With the surface water mode set to Avg Terrain, identified water average areas can be extended to include surrounding terrain within the configured distance.	1000

This allows water on land to be averaged with the waterways. Water on land that can be averaged has to be higher than the configured AVG_TERRAIN_STORAGE_M.

• 
  Water Overlay with set to Grid Averaging Terrains and an average terrain width of 1000m.
• 
  Water Overlay with set to Grid Averaging Terrains and an average shore width of 100m.
• 
  Difference in water level.

Notes

• This option is only used when the surface water mode is set to Avg Terrain.
• As indicated by the range, the average terrain width is converted to a grid cell amount; the average terrain width is divided by the grid cell size.
