Winter has arrived, is there any water in the reservoir?

Winter has arrived, and there is still water in the reservoir. Generally, the water capacity of reservoirs is too large to flow, and the water is deep and there is water. The bottom heat affected by summer is less affected by northwest wind, and the water temperature is higher than the surface temperature. When the temperature drops to zero or even lower in winter, the water in the reservoir is not only deep but also rich.

The rectified river may completely freeze to death and become a glacier. Because the reservoir is deep and there is a lot of water, the surface of the reservoir may freeze below zero or form an ice sheet, but it will not freeze at the bottom of the reservoir, that is to say, the temperature at the bottom of the reservoir is still above zero.

Reservoir action

Reservoir is one of the engineering measures widely used in flood control in China. A comprehensive reservoir with flood storage capacity should be built at an appropriate position in the upstream of the flood control area, and the flood storage capacity of the reservoir should be used to reduce the flood peak flow into the downstream river, so as to achieve the purpose of reducing flood disasters. There are two different ways for reservoir to regulate flood, one is flood detention and the other is flood storage.

Reservoirs, generally interpreted as water conservancy projects to intercept floods and regulate water flow, can be used for irrigation, power generation, flood control and fish farming. It refers to an artificial lake formed by building a barrage at the narrow entrance of a canyon or river.
