A pilot constructed wetland in south Florida, USA, the Everglades Nutrient Removal (ENR) project was modeled with a physics-based integrated approach by WASH123D. Stormwater is routed into the treatment wetland for phosphorus removal by plant and sediment intake. It overlies a highly permeable surficial groundwater aquifer. Strong surface water and groundwater interactions are a key component of the hydrologic processes. The site has extensive field measurement and monitoring that provide point scale and distributed data...
