EROSION RATE OF RESERVOIR DEPOSIT AS REVEALED BY LABORATORY EXPERIMENT
Abstract: The construction of
dams and reservoirs in a river can give significant impacts on its flow of
water and sediment, and can cause long-term morphological changes on the river.
Reservoir sedimentation can reduce a reservoir’s effective flood control
volume, and in some severe cases can cause overtopping during floods. Sediment
deposition against a dam can reduce its stability, and affect the operation of
low-level outlet works, gates, and valves. The abrasive action of sediment
particles can roughen the surface of release facilities and can cause cavitations
and vibration. Sedimentation can also affect a reservoir’s water quality, and
reduce its flood control, water supply, hydropower, and recreation benefits.
Consequently, taking sedimentation into consideration not only in the planning
and design, but also in the operation and maintenance of a dam and reservoir is
important.
