A reservoir has an initial capacity of 45,000 acre‐ft, with an average annual inflow of 63,000 acre‐ft
and a sediment inflow of 180 acre‐ft/yr. The useful life of the reservoir is when only 20% of the
capacity remains. (a) Assuming the sediment capture rate is unchanged and equal to that of the new
reservoir, what would be the lifetime of the reservoir? (b) What are the percentage capture
efficiencies when the reservoir is at 100% and 20% capacities?
