Simulation data (Water Overlay)

The Water Module's simulation can be linked to other models, which add and define more data to be used in the simulation. Some models are automatically connected, and are required for the calculations to take place. Others are optional, and can apply additional detail to the calculations. When the optional models are absent, default behavior is defined.

Terrain elevation TERRAIN_ELEVATION Water Prequel m datum -10000 to 10000 Clamped to range Used for initializing the terrain elevation on this datum. Surface level SURFACE_LEVEL Water Prequel m -10000 to 10000 Clamped to range Used for initializing the surface water level on this datum, both in waterways and on land. Surface u SURFACE_U Water Prequel m/s -10 to 10 Clamped to range Used for initializing the initial speed of the surface water in the x-direction. Surface v SURFACE_V Water Prequel m/s -10 to 10 Clamped to range Used for initializing the initial speed of the surface water in the y-direction. Surface infiltration SURFACE_INFILTRATION Water Prequel m/day 0 to 10 Clamped to range Surface (top part, e.g. roads) vertical infiltration in meters per day. Groundwater depth GROUND_WATER_DEPTH Water Prequel m 0 10000 Clamped to range Used for initializing the ground water level to these depths. Groundwater datum GROUND_WATER_DATUM Water Prequel m datum -10000 10000 Clamped to range Used for initializing the ground water level on this datum. Ground conductivity GROUND_CONDUCTIVITY Water Prequel m2/day or m/day 0 10000 Clamped to range Used for initializing the ground conductivity, with or without thickness.

{{:Ground infiltration

Unsaturated fraction UNSATURATED_FRACTION Water Prequel 0 to 1 Clamped to range Used for initializing the saturation of the unsaturated zone in the underground. Bottom distance BOTTOM_DISTANCE Water Prequel m 0 10000 Clamped to range Used for initializing the bottom distances. Bottom Resistance BOTTOM_RESISTANCE Water Prequel days 0 to 1000000 Clamped to range A grid of values containing the resistance of the lower layer against the bottom boundary flow. Bottom Pressure BOTTOM_PRESSURE Water Prequel m datum -1000000 to 1000000 Clamped to range A grid of values containing the head of the ground water pressure caused by ground water in higher regions outside the project area. Max infiltration MAX_INFILTRATION Water Prequel m 0 to 1000000 Clamped to range Used in Infiltration only mode to limit the maximum amount of storage per gridcell. Manning MANNING Water Prequel 0.01 to 0.255 Clamped to range Used for overriding the surface terrain's manning value. Microrelief MICRORELIEF Water Prequel m 0 to 0.255 Clamped to range Used for initializing the height of microrelief hills.
