Abstract
To assist land-use managers in addressing the problem of erosion, a computer simulation model (SEDCAD) can be used to determine the effectiveness of well-applied erosion-control practices in reducing the loss of soil from actively developing sites. The program includes procedures based on a modified version of the Universal Soil Loss Equation, which is widely used by water resource managers to estimate soil erosion rates over a range of spatial scales. For a construction site in northeastern Ohio, the computer program SEDCAD was used to estimate the changes in off-site sediment delivery that occur when the soil on the site is completely exposed as a result of clearing, grading, and other construction activities. Assuming application of erosion-control best-management practices, ranging from the use of straw mulch to the use of a sediment basin, SEDCAD simulation results indicate that proper management practices can reduce sediment delivery to wetlands adjacent to this site to pre-development levels.
