Surface infiltration is calculated per cell.

First, the infiltration capacities are calculated:

if a construction is present

if no construction is present

Then the actual infiltration:

Where:

  • = 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.
