CE 4200 Chapter : Quiz 1 And Solution
Document Summary
Compute the constant draft (ft3/day) from a 1200-acre reservoir for 30-day period during which the reservoir level dropped 2 ft despite an average upstream inflow of 25 ft3/s. During the period, the total seepage loss was 1 in, the total precipitation was 4 in, and the total evaporation was 3 in. (1 acre = 43560 ft2) Therefore, ( 2ft) 1200ac (4in) 1200ac 25 ft. Note: the negative sign in the storage change ( s ) term is because of reservoir depletion.
