Urban small watershed classification and grading intelligent scheduling method

Abstract

The invention discloses an urban small watershed classification and grading intelligent scheduling method. According to the invention, the method comprises the steps: taking rainfall forecast as a judgment condition; starting different scheduling modes according to the rainfall prediction situation, namely, rain-free starting ecological water supplementing scheduling, light rain starting water environment scheduling, medium rain starting water environment-flood prevention and drainage combined scheduling and heavy rain-rainstorm starting flood prevention and drainage scheduling; automaticallyswitching the scheduling modes along with the change of the rainfall situation, and dynamically adjusting the scheduling scheme. The complex comprehensive scheduling problem of the urban small watershed is decomposed through classified scheduling, so the processing scheduling target is clear, the scheduling model is simple, the calculation efficiency is higher, and the operability is higher; meanwhile, a simulation and optimization combined method is adopted, and a scheduling process is decomposed through a 'plan scheduling-optimal scheduling' two-stage scheduling mode, so the repeated trial process of an optimal scheduling scheme can be skipped, the time is saved, the efficiency is improved, and meanwhile, the method is more practical and more applicable to basic-level scheduling personnel.

Description

technical field [0001] The invention belongs to the technical field of comprehensive watershed scheduling, and in particular relates to a classification and grading intelligent scheduling method for small urban watersheds. Background technique [0002] With the acceleration of economic development and urbanization, water problems such as water ecology, water environment, and waterlogging have become more and more serious. Especially in coastal towns, the regional economy is more developed, the population is denser, and the urbanization is developing faster, causing problems such as water shortage in the ecological landscape of the river, “towns look at the sea” in flood season, and black and odorous river water in non-flood season. In urban built-up areas, the water engineering system consisting of reservoirs, embankments, gate pumping stations, pipeline networks, sewage treatment plants, etc. has been basically completed. Under the existing water engineering system, how to ...

Problems solved by technology

[0004] In terms of urban small watershed regulation, existing achievements focus on single-objective regulation such as water supply, water ecology, water landscape, water environment, and waterlogging. However, in the process of urban development, water issues such as water ecology, water environment, and water security coexist, and single Target scheduling cannot meet actual demand
