Sed-Emmett is an Excel-based sediment basin design tool tailored to complement Tennessee Department of Environment and Conservation's Erosion Prevention and Sediment Control Handbook. Sediment basins are temporary impoundment structures designed to intercept, detain, and treat sediment-laden stormwater from active construction sites. To optimize basin configurations, the tool processes standard site parameters such as drainage area, disturbed acreage, development conditions, and dewatering methodology, alongside innovative inputs like particle size distribution and target treatment size. The true novelty of the Sed-Emmett model lies in its iterative approach converging computations of a particle's settling velocity and critical settling velocity, ensureing the final design is fully capable of removing the pre-specified sediment load.
