A calculation method of ecological water demand based on sluice-dam partition

Abstract

The invention belongs to the technical field of environmental protection, in particular to a method for calculating ecological water demand based on a sluice dam partition, comprising the following steps: 1) each sluice dam and hydrological station on a river course being arranged as a calculation section; 2) calculating the river section accord to the calculation section setting; 3) calculating the ecological water requirement of the calculate section based on the calculated section; 4) calculating the ecological water requirement of the river reach. The purpose of the invention is to providedata support for guiding the joint operation of the reservoir and the gate dam, and to calculate the ecological water demand of the river reach for the section without hydrological data. The invention adopts the sluice dam as the calculation section, and takes the calculated ecological water demand between adjacent sluice dams as the basis of the sluice dam ecological water regulation, which is favorable for the fine regulation of the sluice dam.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for calculating ecological water demand based on gate and dam partitions. Background technique [0002] With the rapid development of social economy and the rapid growth of population, the scarcity of water resources is increasing, and the natural river runoff can no longer meet the demand to a large extent. Out of the needs of production and life, people continue to build water conservancy projects such as reservoirs and dams on rivers to regulate runoff to meet human needs, making most rivers highly controlled rivers, and the increase in production and living water is gradually increasing. Occupying the ecological water volume of the river, the ecological water demand in non-flood seasons is generally insufficient, resulting in worsening hydrodynamic conditions of the river, coupled with water pollution of the river, causing the current eco...

Problems solved by technology

Out of the needs of production and life, people continue to build water conservancy projects such as reservoirs and dams on rivers to regulate runoff to meet human needs, making most rivers highly controlled rivers, and the increase in production and living water is gradually increasing. Occupying the ecological water volume of the river, the ecological water demand in non-flood seasons is generally insufficient, resulting in worsening hydrodynamic conditions of the river, coupled with water pollution of the river, causing the current ecological status of most rivers to be worrying

For the sake of the healthy ecological status of the river, the current common measure is to use the hydrological station as the calculation section to calculate the ecological water demand of the river. This is a macroscopic quantity and cannot guide the fine scheduling of gates and dams.

[0003] The gate and dam are used as the calculation section to calculate the ecological water demand of the river section. At present, there is a lack of relevant hydrological parameters for the gate and dam to be used as the calculation section.
