Abstract
Sediment retained in a 197-m(3) sedimentation basin during 12, two-yea r storms with identical 100-m(3) inflow hydrographs and 454 kg sedigra phs was measured Sediment discharged through the perforated riser and single-orifice principal spillways was similar at 23.1 kg. Of the aver age of 23.1 kg of sediment discharged during each event, 3.0 kg was re suspended from previously deposited sediment, 9.1 kg originated from t he basin floor and sides, and 11.0 kg originated from the soil infecte d during that event. Sediment discharge averaged 13.4 kg for the 0.46- m deep permanent pool and 24.0 kg for the 0.15-m deep permanent pool.
