Abstract

The invention discloses a heavily silt-carrying river water quality and water flow integrated configuration and dispatching method and system. The heavily silt-carrying river water quality and water flow integrated configuration and dispatching method comprises the steps that S1, required data for heavily silt-carrying river water quality and water flow integrated configuration and dispatching modeling is acquired, and a model physical boundary and a parameter threshold boundary are established; S2, a heavily silt-carrying river water quality recovery capability evaluation standard and methodare established; S3, a heavily silt-carrying river water quality and water flow double-control mechanism is established; S4, a heavily silt-carrying river water quality and water flow integrated configuration and dispatching model is established; S5, the heavily silt-carrying river water quality and water flow integrated configuration and dispatching model is solved; and S6, a heavily silt-carrying river water quality and water flow integrated configuration and dispatching scheme is generated and output. The method has the advantages that based on six characteristic rule identifications and water quality recovery capability evaluation of a heavily silt-carrying river, the model is solved with the application of an improved minimum cost and maximal flow theory, the heavily silt-carrying river water quality and water flow integrated configuration and dispatching scheme is optimized and output, so that a new technical scheme is provided for realizing water flow and water quality synchro coupling control and management on the heavily silt-carrying river.

Description

technical field [0001] The invention relates to the optimal configuration of water resources of rivers with many sediments, the scheduling of reservoir groups, the evaluation of water quality recovery ability and the management of water resources, in particular to the method and system for the integrated configuration and scheduling of water quality and quantity of rivers with many sands. Background technique [0002] Water quantity and water quality are two basic attributes of water resources, and the two are interdependent entities. With population growth and economic and social development, the demand for water resources continues to increase, the amount of sewage discharge increases, and the dual pressures on water quality and water quantity continue to increase. The integrated allocation and dispatch of water quantity and quality has become one of the frontiers and hotspots of water science research at home and abroad. . [0003] Literature research shows that the curr...

Problems solved by technology

[0003] Literature research shows that the current research pays more attention to water quality issues, but the research on simultaneous consideration of river water quantity and quality is limited. It mainly focuses on the coupling relationship between water quantity and water quality in river reservoir systems. Through modeling optimization, the allocation scheme of river water quantity and pollution load is proposed. It solves the problem at the configuration level, but there are few studies on the integrated scheduling of water quantity and quality
