V-NOTCH and Flow Meters

Leakage measurement is one of the most important indicator of the overall performance of earth/rock-fill and concrete dams.

The leakage rate is a function of the water level in the reservoir and depends either from the construction than the behaviour of the dam. Consequently, leakage monitoring provides data for the evaluation of the long term stability of the dam constructions.

Leakage water is usually impounded downstream of the dam and diverted to a basin in a weir-station.
