The invention provides a reservoir system in hilly and mountainous areas and a building method thereof. The reservoir system comprises an existing reservoir and a water storage unit system, wherein at least one water storage unit is arranged in a water collecting area of the existing reservoir; the water storage units are distributed in the longitudinal and transverse direction of the existing reservoir to form the water storage unit system. As the water storage units are added to the water collecting area of the existing reservoir to form the reservoir system, the flood control reservoir storage capacity of the reservoir is improved, the flood control capability is enhanced, damage and pollution to the ecological environment are reduced, damage caused by rainstorm to the reservoir and downstream flood disasters of the reservoir are also reduced, and the reasonable water resource utilization degree and level are improved.
Description
technical field [0001] The invention relates to the technical field of water resource protection, in particular to a hilly and mountainous reservoir system and a construction method thereof. Background technique [0002] Reservoirs are one of the widely used engineering measures for flood control in my country. A comprehensive utilization reservoir that can regulate and store floods is built at an appropriate location in the upstream of the flood control area. The reservoir capacity is used to store floods and reduce the peak flow of floods entering the downstream rivers. It has the functions of flood detention and flood storage. To achieve the purpose of reducing flood disasters and promoting profits. However, if the water level of the reservoir is too high due to continuous heavy rainfall, the gate must be opened to discharge the flood downstream. On the one hand, it may cause the downstream to be flooded, and on the other hand, it will cause a waste of rain and flood resou...
