Description
Technical field
The invention belongs to environmental protection technical fields, and in particular to a kind of Water Requirement calculating side based on gate dam subregion
Method.
Background technique
With the rapid development of social economy with the sharp increase of population, rare increasing, the natural river of water resource
River runoff largely can no longer meet demand.For the needs of production, life, people are constantly built on river
Hydraulic engineering such as reservoir and gate dam carry out regulated flow, to adapt to the needs of the mankind, so that most of river becomes high degree of controlled river
Stream, and the increase for the water that produces and live, gradually tie up the environment water volume in river, non-flood period Water Requirement is generally insufficient, leads
Urban river water power situation is caused worse and worse, in addition the water pollution in river, causes the ecological ragime in most of river at present to cause anxiety.
For the ecological ragime of river health, measure universal at present is using hydrometric station as section is calculated, and the ecology for calculating river needs
Water, this is a macroscopical amount, can not be instructed gate dam careful regulation.
Using gate dam as section is calculated, the calculating for calculating section Water Requirement is carried out, shortage gate dam, which is used as, at present calculates
The related hydrologic parameter of section.
Summary of the invention
For the above technical problems, the present invention provides a kind of Water Requirement calculating side based on gate dam subregion
Method, which comprises the following steps:
Step 1, each gate dam on river and hydrology website are set as a calculating section, and the gate dam is with regulating and storing
The gate dam of ability；
Step 2, according to section setting calculating section is calculated, i.e. section between neighborhood calculation section is set as a calculating
Section；
Step 3, based on section is calculated, the calculating for calculating section Water Requirement is carried out；The calculating section water demand for natural service
Amount includes the corresponding basic ecological flow for calculating section, self-cleaning Water Requirement, sediment transport Water Requirement, evaporation water requirement, seeps
Leak water requirement and bank vegetation growth water requirement；
Step 4, according to river water equilibrium principle, the calculating for calculating section Water Requirement is carried out；Calculate section
Water Requirement is equal to the difference that the calculating section both ends calculate the Water Requirement of section.
In the step 3, the calculation method of basic ecological flow and self-cleaning Water Requirement is related to the natural runoff in river
Amount and section flow of the river in the calculating section part, the calculation method specifically:
River day is carried out using the hydrological data at related hydrometric station using Mike software building water quality of river water model
Right streamflow regime and the simulation of streamflow status, obtain and calculate section natural runoff and section flow.
Beneficial effects of the present invention:
The present invention proposes a kind of Water Requirement calculation method based on gate dam subregion, it is therefore an objective to instruct reservoir and gate dam
Combined dispatching provides data supporting.The present invention can also carry out the calculating of section Water Requirement to the section of not hydrological data.
The present invention, as section is calculated, the adjacent gate dam parabiosis water requirement of calculating is dispatched as gate dam environment water volume using gate dam
Foundation, conducive to the careful regulation of gate dam.
The present invention has rational design, it is easy to accomplish, there is good practical value.

For the problems of current river ecological water demand, the present invention provides a kind of ecology need based on gate dam subregion
Water calculation method, as shown in Figure 1, for specifically including step to instruct reservoir and gate dam combined dispatching to provide data supporting
It carries out:
Step 1, each gate dam on river and hydrology website are set as a calculating section, and the gate dam is with regulating and storing
The gate dam of ability；
Step 2, according to section setting calculating section is calculated, i.e. section between neighborhood calculation section is set as a calculating
Section；
Step 3, based on section is calculated, the calculating for calculating section Water Requirement is carried out；The calculating section water demand for natural service
Amount includes the corresponding basic ecological flow for calculating section, self-cleaning Water Requirement, sediment transport Water Requirement, evaporation water requirement, seeps
Leak water requirement and bank vegetation growth water requirement；
Wherein, the calculation method of basic ecological flow and self-cleaning Water Requirement is related to the natural runoff and river in river
In the section flow of the calculating section part, the calculation method specifically:
River day is carried out using the hydrological data at related hydrometric station using Mike software building water quality of river water model
Right streamflow regime and the simulation of streamflow status, obtain and calculate section natural runoff and section flow；
Step 4, according to river water equilibrium principle, the calculating for calculating section Water Requirement is carried out；Calculate section
Water Requirement is equal to the difference that the calculating section both ends calculate the Water Requirement of section.
The present invention proposes a kind of Water Requirement calculation method based on gate dam subregion, it is therefore an objective to instruct reservoir and gate dam
Combined dispatching provides data supporting.The present invention can also carry out the calculating of section Water Requirement to the section of not hydrological data.
The present invention, as section is calculated, the adjacent gate dam parabiosis water requirement of calculating is dispatched as gate dam environment water volume using gate dam
Foundation, conducive to the careful regulation of gate dam.
