TY - JOUR T1 - Sediment trap efficiency of a small reservoir JF - Journal of Soil and Water Conservation SP - 278 LP - 280 VL - 39 IS - 4 AU - F. E. Dendy AU - C. M. Cooper Y1 - 1984/07/01 UR - http://www.jswconline.org/content/39/4/278.abstract N2 - The sediment trap efficiency of a 2.7-acre reservoir was measured during a 2-year period. While the overall trap efficiency was about 77%, monthly trap efficiencies ranged from 9% to 100%. Trap efficiency was generally much higher for storms accompanied by high sediment loads and high sediment concentrations. Trap efficiency was generally low for storms producing low sediment concentrations. Highly variable flow detention times may explain part of the variation in storm trap efficiencies. ER -
