Method for distinguishing suitable scale of hydraulic engineering through improvement of water environment based on single curve knee point method

Abstract

The invention provides a method for distinguishing a suitable scale of hydraulic engineering through the improvement of a water environment based on a single curve knee point method. The method comprises the steps that two related variables are determined, that is, an index W of the water environment needing to be improved and a factor N influencing the index of the water environment are selected; corresponding values of the factor N influencing the index of the water environment under the condition of different hydraulic engineering scales are simulated and calculated; the single curve of the index W of the water environment needing to be improved and the factor N influencing the index of the water environment is drawn, and the range of a knee point is analyzed; the area of the knee point is selected. According to the method for distinguishing the suitable scale of the hydraulic engineering through the improvement of the water environment based on the single curve knee point method, the range of the hydraulic engineering is determined in the range of the area of the knee point, engineering benefits can be effectively achieved, and the problems that investment waste is caused by the too large hydraulic engineering scale, and due to a small engineering scale, the engineering effect is poor and the due engineering benefits cannot be fully achieved are solved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and relates to a method for improving the suitable scale of the water environment, in particular to a method for judging the suitable scale of the water conservancy project for improving the water environment based on a single curve inflection point method. Background technique [0002] At present, there are not many methods to determine the appropriate scale of water conservancy projects from the perspective of water environment improvement. There are generally two methods: one is to calculate the water environment improvement of a given scale based on several scales given by other functions of the water conservancy project. Effect, as an auxiliary means to determine the scale required to realize other functions of water conservancy projects; the other is to determine the scale through formula calculation in a static state, according to the principle of material balance and ...
