Design method of distributed water resource allocation model

Abstract

The invention provides a design method of a distributed water resource allocation model. The design method comprises the following steps: S1, dividing calculation units; s2, designing a topological relation; s3, designing information distribution; s4, designing a configuration module; and S5, designing a configuration rule. By means of modularization and integration thoughts, bidirectional coupling of a water resource allocation model and a distributed hydrological model SWAT is achieved, and the invention has the functions of natural-artificial water circulation dynamic mutual feedback simulation, water resource system and reasonable allocation simulation and the like; the problems that a traditional water resource allocation model neglects the dynamic mutual feedback effect between natural water circulation and artificial lateral branch circulation and cannot respond to the influence of dynamic changes of production and confluence on water resource allocation in real time are solved, and the accuracy of water resource system simulation and regulation and control is improved. The invention can be used as a powerful supporting tool for regional natural-artificial water circulation mutual feedback simulation and fine management of a water resource system.

Description

technical field [0001] The invention relates to the technical field of coupling calculation of a hydrological model and a water resource allocation model, in particular to a design method of a distributed water resource allocation model. Background technique [0002] The traditional water resource allocation model is a lumped model. In terms of space, the spatial differences in natural geographical conditions and human activity intensity in the calculation zone are ignored, and the calculated value on this basis only represents a concept of the average configuration zone, which is easy to ignore the water resource problem in a specific location; in terms of time, Generally, the step size is calculated month by month or ten days, which cannot respond in real time to the impact of dynamic changes in production and confluence on water resource allocation. [0003] With the development of distributed hydrological models becoming more and more mature, some scholars have proposed...

AI Technical Summary

Problems solved by technology

[0004] However, the coupling mode of the distributed hydrological model and the water resource allocation model is mostly loose coupling

Although the spatial variability of the region and the water cycle process are considered, the dynamic interaction between the natural water cycle and the social water cycle process is ignored, resulting in deviations in the results of water resource allocation, which is not conducive to the fine simulation and regulation of the natural-artificial water resource system.
