Surface infiltration formula (Water Overlay)

Surface infiltration is calculated per cell.

First, the infiltration capacities are calculated:

${\bar {I_{t}op}}={\begin{cases}{\bar {I_{con}}},&{\text{if constructions are present on top of the surface}}\\{\bar {I_{terrain}}},&{\text{otherwise}}\\\end{cases}}$

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 I_{surface} = min(\bar{I_{ground}}, \bar{I_{top}}}) Then the actual infiltration: <math>\Delta w = min( h, \Delta t \cdot I_{surface})}

Where:

{\bar {I_{con}}}

= The average infiltration speed based on constructions on top of the surface, based on GROUND_INFILTRATION_MD.

{\bar {I_{terrain}}}

= The average infiltration speed based on the surface terrain, defined by GROUND_INFILTRATION_MD. This value should be interpreted as the vertical conductivity (Kv) of the sub-soil.
