Method for diverting water in a plain urban river network

Abstract

The invention discloses a method for diverting water in a plain urban river network. The method includes material collection, on-site measurement, prototype observation and mathematical model computing, scientific water resources controlling and reasonable configuration, and diversion and drainage planning. The aforementioned steps can enable diverting water in the river network smoothly, can increase water velocity and height of water, the water fluidity and capacity, so that the water quality and landscape of the urban river network is improved. According to the invention, the method, by on-site debugging and analyzing and sorting basic data of a mathematical model, proposes a water diverting engineering plan which enables real-time adjustment on the basis of river flow capacity, realizes staged diversion and diversion according to needs, and also increases water function of rivers and sensory index of a city; the method performs computing and analysis in combination with water-volume and water quality refining mathematical model, pollution load source elimination method and water diverting engineering plan, enables collective arrangement of water diverting routes, water diverting time, hydro-engineering and water diverting engineering, and enables the function of the plain urban river network to reach standards.

Description

technical field [0001] The invention relates to the field of plain urban water environment, in particular to a method for smooth and flowing water in a plain urban river network. Background technique [0002] Running water is the soul of the entire water quality improvement plan. Now the rivers in the plain cities are interconnected, the water level is flat, and the flow is slow; Closed operation makes it more difficult for the water in the urban river network to flow; relying on the forced drainage of pumps and gates in the urban area, local water bodies can exchange and flow, but because the scale of water transfer is too small, the effect of flowing water is still not good despite the frequent use of pumping stations Well, there is not much time for running water, and the range of running water is very small. On the whole, the small and medium circles inside the city are like a few small and medium circles, disturbed by many water pumps, but the big circle of the city is ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a method for smooth and flowing water in the river network of plain cities to solve the problems raised in the above-mentioned background technology: (1), the river network of plain cities is intricate, and the tidal volume of rivers, transit water resources or high-quality water sources in the upper reaches are obtained. Without utilization, the size of the urban river network is surrounded by internal circulation, and because the plain urban rivers are gentle, the river flow is slow, and the lack of dissolved oxygen in the water makes the sediments in the rivers degrade slowly, resulting in poor water quality and poor water landscape; (2), Some cities around the rivers are densely populated and water resources are scarce, and some rivers are sparsely populated and have excess water resources, which makes the city's sensory indicators poor; (3), the existing water diversion routes, water diversion timing, water conservancy projects and water distribution The project does not have a scientific and unified dispatching plan, and the utilization rate of water conservancy facilities and water distribution facilities is low, which makes the utilization rate of water environment resources in plain urban water function areas low
