Abstract
Wetlands are unique, diverse, and productive habitats in the natural environment. They have significant ecologic values due to their potential to deposit, sediment, and filter out pollutants from the water that flows through them. Wetlands have been investigated from different aspects in the past years; however, the computer modeling of the complex processes that occur in wetlands has attracted less attention. In this study, the mechanism of pollutant removal has been studied by developing a new template for the ecological modeling of the wetlands. The kinetics of oxygen balances, biochemical oxygen demand, coliform, and nutrient removal are numerically simulated. To explore modeling capabilities, a wetland in northern Iran, was investigated as a case study. Field measurements were performed for parameter estimations and model calibration. The numerical results exhibited that concentrations of BOD, total coliform, phosphate, and nitrate decreased up to 45%, 44.96%, 44.8%, and 43.47%, in the outflow when model has run for spring and summer seasons and the results compared to the field sampling data.
