Because of the climate in our country, a certain place is flooded every year, and such a local subway station becomes a water curtain hole. In order to reduce the occurrence of floods, the government has built many reservoirs with flood storage function, but when the water in the reservoirs exceeds the water level line, flood discharge measures have to be taken, so why don't the reservoirs discharge flood in advance? Follow me to find out!
When the 0 1 reservoir is completed, many experts accurately calculate its compressive capacity according to its construction materials, depth and size, and then give the maximum storage capacity of the reservoir and draw the highest water level line.
When it rains continuously, if the water level line does not reach the highest position, it is not easy to discharge water and flood, because flood discharge has a great influence on the flood discharge area below, from the light road to the stream and then to the heavy river; However, beyond this water level line, the reservoir is in danger of breaking its banks, and it is necessary to ask the superior before releasing water.
The famous reservoirs in China include Three Gorges Reservoir, Danjiangkou Reservoir, Xin 'anjiang Reservoir, Wang Ying Reservoir, Miyun Reservoir, Shangzhuang Reservoir and Guanting Reservoir.
