Background

In the middle and small size reservoirs in large quantity in China, most of the reservoirs are built by soil and stones in the fifties to seventies of the last century. 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 monitoring of seepage flow mainly has weir type flow measurement boards such as triangular thin-wall weirs, trapezoidal weirs and the like, the devices can indirectly measure the flow by measuring the height of a liquid level, the flow flowing through a weir crest or a notch and the height of the weir crest meet a certain unit value relation according to a mechanical principle, so the seepage flow of a dam can be calculated only by measuring the height of the weir crest, the water depth in the existing reservoir seepage open channel is usually less than 1 meter, and outside measuring personnel are inconvenient to put a flowmeter into water for measurement, thereby influencing the measuring progress.
