Research
The Tan Brook is a heavily channelized stream that runs through an urbanized watershed in Amherst, MA. It poses a stormwater management problem for the University of Massachusetts Amherst due to flooding of soccer fields and erosion of a drainage ditch. The purpose of this study was to estimate reductions in runoff volume to the Tan Brook based on the hypothetical implementation of permeable pavements in various combinations of parking lots, driveways, roadways, and sidewalks, which cover 26% of the watershed area. A spreadsheet model-based approach utilized the Watershed Treatment Model to estimate runoff volume. The percent imperviousness of various …
