Abstract : Wetlands can effectively remove pollutants from wastewaters and runoff, thus improving water quality. Methods are needed for estimating the amount of pollutant removal and water quality improvement provided by wetlands. A screening-level, analytical model is needed for rapid assessment of this wetland function. This report presents analytical model formulations for predicting pollutant RE provided by wetlands. These formulations have been programmed into an interactive, user-friendly, PC- based computer program, which is also described in the report. Comparisons of predicted versus observed REs for the Cache River wet- land, Arkansas, are made for total suspended solids, total nitrogen, and total phosphorus.
