Problems solved by technology

In addition, the current "Interim Measures for Compensation for the Use of Flood Storage and Detention Areas" has problems such as difficulties in implementation, inaccurate loss estimates, and unsmooth compensation work in practice, which has caused decision makers to take a relatively conservative attitude towards the use of flood storage and detention areas.
The current standard setting for the use of flood storage and detention areas is too high, and the compensation for use is difficult to implement, which is an important factor restricting the full play of the benefits of cascade reservoirs in the flood season, and there are major defects

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] figure 1 For the concrete flow chart of this method, concrete steps are as follows:

[0026] Step 1: Collection of basic watershed data. Including reservoir inflow conditions, dispatching rules, flood control objectives, etc.; information investigation of flood storage and detention areas, including basic information of river basins, social and economic conditions, general investigation of wading projects, investigation of historical floods, investigation of dangerous areas, detailed investigation of important villages and towns along the river, and important control Cross-section measurement, operating conditions for flood diversion and storage, historical operating conditions, etc.;

[0027] Step 1 is a routine step in this technical field.

[0028] Step 2, drawing the basin flood control risk map and dividing the risk areas. Using GIS technology combined ...

Abstract

A river basin cascade reservoir and detention and retarding basin joint scheduling method comprises the following steps: S1, collecting the basic data of a river basin; S2, drawing a river basin flood risk chart and dividing risk areas; S3, acquiring precipitation, runoff forecast data and reservoir operation data of reservoirs and ranges in real time; S4, by taking the forecast and operation data in S3 as input, establishing and solving a reservoir group and detention and retarding basin joint real-time scheduling multi-objective optimization model; and S5, enabling detention and retarding basin compensation calculation. The method can give full play to the flood control and economical benefits of detention and retarding basins, and can be widely used in reservoir group and detention and retarding basin joint scheduling. Sustainable development of detention and retarding basins is taken into full consideration by enabling a compensation mechanism. A new scientific decision-making approach is provided for river basin flood control scheduling.

Description

technical field [0001] The invention relates to the technical field of flood control dispatching, in particular to a joint dispatching method of cascade reservoirs and flood storage and detention areas in a river basin. Background technique [0002] my country is one of the countries most frequently and seriously affected by flood disasters in the world. Many rivers have the characteristics of large peak heights and large changes in flood and dryness, and the main rivers generally have insufficient flood discharge capacity. Usually, it can only be used in conjunction with embankment projects. Reach the flood control standard once in 10 to 30 years (Liu Shukun. Analysis on the development trend of foreign flood control and disaster reduction [J]. Water Conservancy and Hydropower Science and Technology Progress, 2000,20(1):2-9.). For a long time, my country's river basin flood control system has taken reservoirs as the core component, and reservoirs are also the only active flo...
