Surface infiltration is calculated per cell.

First, the infiltration capacities are calculated:

Cwater = Wsurface
Ctop = max( Icon, Isurf )
Isurf = 0 if a construction is present
Icon = 0 if no construction is present

Then the actual infiltration: Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \Delta w = min( C_{water} , \Delta t \cdot C_{top})<\math> Where: * <math>\Delta w} = The surface infiltration which takes place.

  • = Computational timestep.
  • = The amount of infiltration that can take place based on the amount of water on the surface.
  • = The amount of infiltration that can take place based on the infiltration values present.
  • = The amount of water (the water column) on the surface.
  • = The GROUND_INFILTRATION_MD of a construction on a specific cell (if present).
  • = The GROUND_INFILTRATION_MD of the surface terrain type. This value should be interpreted as the vertical conductivity (Kv) of the sub-soil.
