Due to the fact that the compaction degree of the earth-rock dam body is limited, the dam always leaks to different degrees. When the upstream water level of the reservoir changes, the water flow leaked from the dam body also changes along with the change. The interior of the dam body of a reservoir which runs for many years gradually tends to be uniform and stable, so the rule of the seepage flow along with the change of the upstream water level also tends to be stable. Therefore, the size of the seepage becomes an important index for measuring whether the reservoir dam operates safely, and according to the technical specification of earth-rock dam safety monitoring, workers must check the seepage quantity of the dam every day, so that the workload of the workers is increased.
At present, the seepage flow monitoring mainly comprises a triangular thin-wall weir, a trapezoidal weir and other weir type flow measuring plates, the devices can indirectly measure the flow by measuring the height of a liquid level, and according to the mechanical principle, the flow flowing through a weir crest or a notch and the height of a weir crest water head meet a certain unit value relationship, so that the seepage flow of a dam can be calculated only by measuring the height of the weir crest water head.
