Methods of Flood Regulation and Water Resources Security under Changing Environment and Rapid Flood and Drought Conditions

Abstract

The invention discloses a method of flood dispatching and water resources guarantee under the conditions of changing environment and sudden flood and drought. A water resource guarantee simulation model; establish and analyze a water resource guarantee scheme; based on the water resource guarantee simulation model, call a pre-stored water resource supply and use simulation method, and carry out the guarantee level of the water resource guarantee scheme under each set scenario Simulation, screening of water resource security schemes that meet the expected set conditions, forming a water resource security scheme system. The invention forms a regional water resource security scheme under multiple scenarios, establishes a demonstration project for improving water resource security capabilities, increases the water resource security rate in dry seasons by more than 10%, and solves flood dispatching and water resource security under conditions of changing environments and sudden floods and droughts The problem.

Description

technical field [0001] The invention relates to a related method of water resource scheduling, in particular to a flood scheduling and water resource guarantee method under the conditions of changing environment and abrupt changes in flood and drought conditions. Background technique [0002] Water shortage has become one of the important factors restricting the sustainable development of economy and society. With the continuous acceleration of industrialization, the situation of water shortage will be more severe. [0003] With the rapid economic and social development, the situation of water resources security is undergoing significant changes, and the contradiction between the existing water resources system and the increasing security needs of social and economic development is becoming increasingly prominent. In order to ensure the water resources scheduling requirements of normal water delivery throughout the year, especially in the new situation of water resources sec...

Problems solved by technology

[0004] In some areas, the types of regional water conservancy projects are complex, including gate and dam dispatching projects, reservoir group regulation and storage projects, and flood diversion projects to the east. Under the condition of sudden flood and drought, the decision-making and optimization method of flood dispatching and water resources guarantee scheme of engineering group restricts the formulation of joint dispatching technical scheme of regional water security guarantee
