Method and system for joint optimization scheduling of flood prevention, waterlogging drainage and running water of plain city river network

Abstract

The invention discloses a method and system for joint optimization scheduling of flood prevention, waterlogging drainage and running water of plain city river network. The method comprises the following steps: S1, judging whether a warning water level is exceeded or not according to a real-time river network water level and 24-hour weather forecast; S2, automatically selecting a scheduling targetand a corresponding scheduling scheme library according to a judgment result; S3, judging a waterlogging level or a water shortage level according to the judgment result, and selecting a correspondingconstraint condition; S4, Using the water quantity-water quality model to solve the scheduling scheme library based on different constraints, and obtain the optimal scheduling scheme. The urban rivernetwork water level can be monitored in real time; The water level amplitude of the river network is measured and calculated in combination with 24-hour weather forecast, on this basis, different waterlogging levels and different drought levels are dispatched differently, meanwhile, the requirements for water resource optimization dispatching and water environment improvement of the urban river network can be met, and the urban water safety level and decision-making efficiency are improved.

Description

technical field [0001] The invention relates to a method and system for combined optimal dispatching of flood control, drainage and running water in plain urban river networks, belonging to the field of urban river network water environment safety. Background technique [0002] At present, cities in the Yangtze River Delta and Pearl River Delta regions with well-developed water systems have basically formed relatively mature flood control systems. However, some wading projects in the flood control system, such as gates and pumps, cut off the natural connection between rivers and lakes, which can easily cause water stagnation and water quality deterioration in the region. With the process of urbanization, the deterioration of urban river network water environment is becoming more and more serious. Therefore, some cities have entered into the water quality improvement plan based on urban flood control and drainage, and the demand for technical support such as joint optimizati...
