SubWet 2.0
Subsurface Wetland Modelling Software


SubWet 2.0 cover image The Subsurface Wetland Model software SubWet 2.0 has been developed to support the decision-making process by assisting experts and water managers in the design of constructed wetlands to improve water quality and treat domestic wastewater. Furthermore, SubWet 2.0 can also be used as a tool to improve the efficiency of low or non-performing systems and model different operational scenarios such as higher or lower volumes or higher or lower concentrations of contaminants. Due to its characteristics this software is very useful for training technicians and students who are interested in modelling artificial wetlands.

SubWet 2.0 is an upgraded version of SubWet allowing for its application in cold as well as warm climates. It simulates removals of nitrogen (including nitrogen in ammonia, nitrate and organic matter), phosphorus and BOD5 in mg/l and the corresponding removal efficiencies (in %). Although the model has been calibrated already with data from cold and warm climates, users can further calibrate and validate it using local data observations.
