- | The wetlands are water classes, but simulated as a soil class with special functions. If the soil is over saturated the standing water is the water volume of the wetland (//vol//, m3). If the soil is not over saturated, the wetland is dried out. The wetlands area (//area//, m2) is defined by the class area, and the depth (//w//) varies with flow. A threshold (//w0//) for the wetland outflow above the soil surface keep water in the wetland. The wetland outflow is determined by a rating curve above this threshold (see also [[start:hype_model_description:hype_routing#common_lake_processes | lake outflow]]). The thresholds can be set by parameters or if parameters are not set it is equal to minus the streamdepth (from GeoClass). | + | The wetlands are water classes, but simulated as a land class with special functions.
