The design of the La Leche dam in Peru requires an asessment of reservoir sedimentation.
Assess the design life of the reservoir, using a turbidity of 2. 5 kg/m3.
The reservoir volume is 80 hm3.
The drainage area at the damsite is 907.36 km2.
The mean annual discharge is 6.44 m3/s.
The specific weight of sediment deposits is 13,000 N/m3.
Assume the worst-case scenario for sediment size.
Assume that bed load (sediment transport by rolling and sliding along the bed) and the unmeasured load amount to
40% of the suspended load.
Calculate the time it will take to fill 20%, 50%, 80% and 100% of the reservoir volume.
