Location conditions of reservoir construction

1. There must be a basin or depression for storing water in this area. The contour line of this terrain is bag-shaped, with a vast hinterland and a large reservoir capacity.

2. The dam should be built at the contour line near the closed section and at the narrowest part of the canyon, so as to reduce the engineering quantity, save investment and ensure the safety of the dam.

3. The geological structure needs to be stable.

4. Consider the situation of land occupation and relocation, and minimize the inundation of fertile fields and villages and towns.

5, but also pay attention to the construction of reservoirs, water should be sufficient.

Extended data:

After the reservoir is completed, it can play a role in flood control, water storage irrigation, water supply, power generation, fish farming and so on. Sometimes natural lakes are also called reservoirs. Reservoirs are usually divided into small, medium and large reservoirs according to their storage capacity.

In the stage of reservoir management and operation, if water can be used before the flood season, the reservoir water level will drop to the reservoir flood limit level, and the reservoir flood limit water level will be lower than the spillway crest elevation.

Part of the flood stored in the reservoir can play a planned role in the dry season. When the spillway is equipped with gates, the reservoir can play a greater role in flood storage.
