WetQual-GUI

This Graphical User Interfaces (GUI) was developed for the Wetland Water Quality Model, WetQual. The process-based WetQual model simulates nitrogen (N), phosphorus (P), total suspended sediment (TSS) and carbon (C) cycles and their dynamics in wetlands. The model partitions a wetland into three basic compartments: (1) (free) water column, (2) wetland soil layer, which is further portioned into aerobic and anaerobic zones, and (3) plant biomass.
