 == Exception: pavement ==

+It is possible to account for urban land surfaces such as roads by adding a pavement layer to the soil model. This is realized by setting the parameter {{{veg_type = 20}}}. The pavement is steered via a depth ([wiki:doc/app/lsmpar#pave_depth pave_depth]), a heat capacity ([wiki:doc/app/lsmpar#pave_heat_capacity pave_heat_capacity]), and a heat conductivity ([wiki:doc/app/lsmpar#pave_heat_conductivity pave_heat_conductivity]). The pavement then replaces the upper soil layers up to a depth of {{{pave_depth}}}. In case that {{{pave_depth}}} is between two soil layers, the respective heat conductivity and heat capacities are linearly interpolated between the soil value and the pavement value to the respective grid point.

+The pavement is able to hold a maximum liquid water column of 1 mm from precipitation, which can also evaporate. The soil below the pavement is assumed to be completely dry.
