The infiltrat In 3Di, the infiltration rate in mm/day is defined for each subgrid cell. The infiltration is computed per computational cell. Therefore, the infiltration rate per pixel is translated to values per computational cell and can depend on the water level. -When using the subgrid method, water starts filling a cell from the lowest subgrid cell. When simulating rainfall-runoff scenarios, the overall water depths are relatively small. Therefore, often only a small part of a computational cell is wet. If the infiltration rate is low in the wet part of the cell, the infiltration will be limited. However, in reality rain falls over a full spatial domain, and reaches the lowest areas only after a while. It might be infiltrated before it reaches those areas. Therefore, the total infiltration rate per computational can be made dependent of the rain. A user does not only define the infiltration rates, but also the *infiltration_surface_option* which can be found in the global settings table. In Fig. 29, an overview of the various types is given. +When using the subgrid method, water starts filling a cell from the lowest test subgrid cell.
