Computer models may assist engineers in planning grade control structures and erosion control practices to reduce sediment yield from unstable watersheds. Bed and bank materials from channels largely contribute to be sediment yield. The numerical channel evolution model BEAMS is capable of predicting the long-term runoff of graded sediment through channel networks. BEAMS computes channel bed scour and fill, lateral erosion at the bank toe, and width adjustment due to mass wasting. Application of BEAMS to Goodwin Creek in northern Mississippi from a companion study indicates that BEAMS accurately predicts sediment yield.
