Porous constructions
Some constructions can porous or open and can allow water to infiltrate into the underground unsaturated zone. Examples of such constructions are grass, bushes, trees or specialized roads and parking lots.
The speed at which water can infiltrate is dependent on both the infiltration properties of the constructions as well as on the underlying surface terrain. The infiltration value that will end up in the grid cell will be the minimum value of the infiltration values of the construction and the surface terrain. This also means that if either has an infiltration value of 0, water cannot infiltrate into the underground unsaturated zone.
