CIV E 638 - SEDIMENTATION ENGINEERING FALL 2022 HOMEWORK No. 2:   SEDIMENT PRODUCTION AND YIELD Using ONLINE_LANE_KOELZER, calculate the specific weight of a sediment deposit in a reservoir after an elapsed time of 50 years, with the sediment always submerged. Assume the following grain size distribution: sand, 25%, silt, 45%, clay, 30%. Use: (a) SI units, and (b) U.S. Customary units. Using ONLINE_USLE2, calculate the watershed soil loss for the same data as Example 15.3 in the textbook. However, use Marshall silt loam in all subwatersheds. Using ONLINE_DENDY_BOLTON, calculate the sediment yield for a 105.6-mi2 watershed with 4.5 in of mean annual runoff.
