TRAP EFFICIENCY (E)

It is define the percentage of the sediment deposit in the reservoir even inspire of taking precautions and measures.
Most of the reservoirs tap 95% to 100% of the sediment load flowing into them.
It has not been possible to reduce the trap efficiency below about 90% inspire of several sediment control measures now know to us.
Trap efficiency is a measure of reservoir sedimentation.
