Screening-Level Model for Estimating Pollutant Removal by Wetlands

摘要

Wetlands can effectively remove pollutants from wastewaters and runoff, thusimproving water quality. This report presents analytical model formulations for predicting pollutant removal 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 removals for the Cache River wetland, Arkansas, are made for total suspended solids, total nitrogen, and total phosphorus.
