# Wetlands

Wetlands are HRUs in which ponding of water on the surface is allowed. There are two files that are specific to wetlands:

* Main wetland file: [**wetland.wet**](wetlands/wetland.wet)
* Wetland hydrology: [**hydrology.wet**](wetlands/hydrology.wet)

For defining the remaining wetland properties, the following reservoir files are used:&#x20;

* Wetland initialization: [**initial.res**](reservoirs/initial.res)
* Wetland sediment: [**sediment.res**](reservoirs/sediment.res)
* Wetland nutrients: [**nutrients.res**](reservoirs/nutrients.res)
* Wetland release: [**res\_rel.dtl**](broken-reference)
