System and method for constructing reserve water source reservoir by utilizing flood storage polder

Abstract

The invention provides a system and method for constructing a reserve water source reservoir by utilizing a flood storage polder. The system comprises a safe flood storage module, a water quality purification module and a water quantity allocation module which are respectively responsible for controlling flood guide, storage and drainage and embankment safety, carrying out the stage purification, improving the water quality of stored and detained flood, and coordinating the flood control reservoir capacity and the reserve water source reservoir capacity. According to the system and the method, gates are in communication with the inside and outside of the polder and channels and reservoirs in the polder, through independent opening and closing operation, the time and water quantity of flood guiding, storing and draining can be accurately controlled, it is guaranteed that sufficient reservoir capacity is provided for regulating and storing flood in the flood, water can be stored at the end of the flood, and the reserve water source can be supplemented, so that the water storage space of the polder is safely, reasonably and orderly applied; and in addition, through combined application of a series of physical, chemical and biological graded water quality purification measures, the storage and detention flood with large sand content and many pollutants is purified to the level for production and life use, and the stable reserve water source is provided for social and economic activities in the polder.

Description

technical field [0001] The invention relates to the field of flood control and disaster reduction and utilization of water resources, in particular to a system and method for constructing a reserve water source reservoir by using a flood storage embankment. Background technique [0002] The polder is an important flood control project in the Yangtze River Basin, and it is widely distributed in the Dongting Lake, Poyang Lake area in the middle reaches and the plain water network in the lower reaches. The polder is separated from the external rivers and lakes by dikes. The internal terrain is low and flat, the population is densely populated, and the agriculture, forestry, animal husbandry, fishery and processing industries are developed. The dikes carry out normal production and life in normal times, and in the flood season, the dikes can be breached to take in water, divert the flow of rivers and lakes, and reduce the flood control pressure of the Yangtze River.
