Risk evaluation method of flood resource utilization of water transfer engineering

Abstract

The invention discloses a risk evaluation method of flood resource utilization of water transfer engineering, and belongs to the technical field of risk evaluation of flood resource utilization of water transfer engineering. The method comprises the following steps: step 1, obtaining basic data of flood resource utilization of the to-be-studied engineering; step 2, constructing a risk evaluation system of flood resource utilization of the water transfer engineering; step 3, determining risk evaluation levels and standards of flood resource utilization of the water transfer engineering; step 4,calculating flood resource utilization risks of water storage engineering, water transfer engineering and water pumping engineering risk indicators; step 5, coupling objective weights calculated andobtained by an entropy weight method and a projection pursuit method and initial weights calculated by an analytic hierarchy process, and using a combined weight method to calculate index weights; step 6, calculating indicator membership degrees through a conditional cloud generator; and step 7, obtaining an overall evaluation level. The combined weight cloud model-based risk evaluation method offlood resource utilization of the water transfer engineering provided by the invention provides a basis for safe flood resource utilization of the water transfer engineering.

Description

technical field [0001] The invention belongs to the technical field of risk assessment of flood resource utilization of water diversion projects, and relates to a risk assessment method of flood resource utilization of water diversion projects based on a combined weight cloud model. Background technique [0002] In recent years, with the rapid development of social economy, the contradiction between supply and demand of water resources has intensified. The cross-basin water transfer project can alleviate the shortage of water resources to a certain extent, but water transfer is generally carried out during the non-flood season. If water transfer is also carried out during the flood season to make full use of flood resources, the problem of water resource shortage in my country can be effectively solved. Taking the east route of the South-to-North Water Diversion Project as an example, the amount of water coming in during the flood season is abundant every year. If the utiliz...

AI Technical Summary

Problems solved by technology

There are differences in the water conservancy project structure, operation characteristics, role in the development and utilization of flood resources, risk value and influence on social and economic development of various flood resource utilization measures of water diversion projects, and a simple weighted summation form cannot be used to determine Assess its flood resource utilization risk
