Abstract

The invention relates to a plain area urban river network water circulation regulation and control method based on an ecological restoration target, and the method comprises the steps: building a water volume-hydrodynamic force-water quality-water ecological index system through the investigation of the basic conditions of an urban river network and taking the aquatic organism diversity as the basic target of the urban river network water ecological restoration; constructing a river network hydraulics-water quality-water ecology refined simulation model, optimizing a flowing water engineeringregulation and control scheme by utilizing a hydrodynamic force-water quality simulation result of each scene scheme, constructing an urban river network large circulation system, and adjusting a section structure of a local end river segment to realize local small circulation; and comprehensively evaluating the flood control safety, the environment improvement benefit and the influence on the water supply source of the regulation and control scheme. Under an existing engineering system, a flowing water source and kinetic energy of the flowing water source are fully utilized, dispatching of hydraulic engineering such as gates and pumps serves as a main way, ordered movement of inland river water flow is promoted, and the inland river self-cleaning capacity is recovered and improved.

Description

technical field [0001] The invention relates to a method for regulating and controlling the water cycle of urban river networks in plain areas based on ecological restoration objectives, and belongs to the technical fields of black and odorous river control and water conservancy engineering. Background technique [0002] "Ask how clear the canal is? For the source of flowing water." Insufficient source water, poor source water quality, and poor hydrodynamic conditions are the main reasons for the deterioration of water environment quality and the degradation of water ecosystems in urban rivers in plain areas. In terms of engineering, in response to the problem of insufficient source water in the urban inland water network in the plain area, a large number of ecological water replenishment practices for urban inland rivers have been carried out, such as the Suzhou City Living Water Artesian Project. Running water is the soul of long-term management of urban water bodies. Run...
