Problems solved by technology

Raising the flood limit water level will increase the water storage capacity of the reservoir, turning the useless discarded water into usable water storage, which reduces the flood control storage capacity, which will inevitably lead to a series of risks and bring greater economic losses to the reservoir area inundation

Embodiment

[0045] The present invention will be described below with specific examples.

[0046] Step 1. Obtain the basic information on the utilization of reservoir flood resources in the research area.

[0047] Basic information on the utilization of reservoir flood resources in the research area, including: characteristic water level of the reservoir, historical flood data of the reservoir, water resources bulletin, and statistical yearbook.

[0048] Step 2. Based on the adjustment of the flood limit water level of the reservoir, a risk decision-making model for the utilization of reservoir flood resources is constructed.

[0049] The reservoir flood resource utilization risk decision-making model constructed by the present invention is:

[0050] (1) Minimum risk rate target:

[0051]

[0052] (2) The goal of maximizing risk benefit:

[0053]

[0054] (3) Minimum risk loss target:

[0055]

[0056] where f 1 is the minimum target of risk rate; w j is the weight value of...

Abstract

The invention discloses a risk decision method for utilizing reservoir flood resources, belonging to the technical field of reservoir flood resources utilization. The method comprises the following steps: step 1, acquiring the basic information of the reservoir to be studied; 2, constructing a flood resource utilization risk decision model of that reservoir based on adjust the limited water levelof the reservoir in the flood season; 3, identifying that risk factors of the reservoir flood resource utilization by the analytic hierarchy process, and determining the main risk factor; 4, calculating that risk rate of each risk index by adopting probability theory and mathematical statistic method, and obtaining the comprehensive risk rate; 5, base on C-D Production Function Method and Emergy Method, calculating Risk and Benefit; 6, calculating that risk loss base on the flood submerged area and the unit area loss method; 7, solving that risk decision model by the constraint method; 8, determining an optimal balanced flood limit water level adjustment scheme for that utilization of the reservoir flood resources. The invention provides a theoretical basis for the safe utilization of flood resources.

Description

technical field [0001] The invention belongs to the technical field of utilization of reservoir flood resources, and relates to a risk decision-making method for utilization of reservoir flood resources. Background technique [0002] With the rapid development of my country's economy and rapid population growth, the contradiction between supply and demand of water resources has further intensified, and various water problems have become prominent. For a long time, people have always associated floods with disasters. However, floods have the attribute of fresh water resources. Using modern technology to break through some flood control scheduling parameters and rules in the design and optimize reservoir scheduling can alleviate the current shortage of water resources. Flood resources, as unconventional water resources, have risks while utilizing flood resources to generate social and economic benefits. Reservoir flood limit water level adjustment is an effective measure for ...
