Flood control decision support method, electronic equipment, storage medium and system

Abstract

The invention relates to a flood control decision support method and a flood control decision support system. A flood forecasting model integrates forecasting of rainfall space-time distribution, runoff generation and confluence calculation, tide level forecasting, river water power calculation and floodplain processing, a modern flood control perception system is combined with the flood forecasting model, a multi-scenario dynamic simulation method is constructed to improve the timeliness and accuracy for prejudgment and forecasting of flood, real-time drawing of a flood risk map, flood influence analysis, flood situation analysis and flood scheme comparison functions are provided, flood information is delivered through multiple channels, and the support is provided for the flood control decision. The invention also relates to electronic equipment and a computer-readable storage medium. A computer program executes the flood control decision support method through a processor; compared with the conventional hydraulic attention object, six types of urban flood risk objects including residence of residents, public transport, basic guarantee, important places, dangerous objects and easily affected representative points are further constructed, a flood risk analysis result is closely related to the actual demand of urban flood control and the socialization attribute of the flood risk prejudgment and forecasting result is improved.

Description

technical field [0001] The invention relates to the field of urban flood control and disaster reduction, in particular to a flood control decision support method, electronic equipment, storage media and a system. Background technique [0002] In recent years, with the acceleration of urbanization and global warming, the frequency of urban flood disasters has been high. In my country's flood season, "the city looks at the sea" has become the norm, and the social and economic losses are huge. Urban flood disasters have become a constraint on the sustainable development of the social economy. the bottleneck. How to improve flood disaster prediction, early warning and emergency response, minimize the loss of urban flood disasters, and cooperate with the society to achieve disaster prevention and mitigation has become a current research hotspot. The key tasks of urban flood control and drainage capabilities require strengthening the construction of urban early warning systems, im...

Problems solved by technology

At present, with regard to the research on urban flood disaster forecasting and early warning, similar or similar achievements at home and abroad mainly include: In terms of flood calculation and analysis models and methods, there are mainly commercial models such as DHI-Mike, Infoworks, and SWMM. Due to the "black box" of the source code, Due to the limitations of relevant computing interfaces and the complexity of real-time urban flood control, the commercial model of flood calculation and analysis is mainly used in planning and design of water conservancy calculations, which is difficult to apply to the actual decision-making of urban flood control; in terms of flood monitoring and early warning software, there are mainly provincial The city's flood control command platform, monitoring and early warning platform, etc., mainly focus on monitoring the city's real-time water and rain work information, and issue early warnings based on the comparison between monitoring data and early warning thresholds, which are relatively empirical and lack a certain period of forecast; In terms of risk attention indicators, it mainly focuses on water conservancy objects such as submerged water depth and submerged range, and does not highlight the social attributes of cities

[0003] Aiming at the problems of low domestic urban flood disaster forecasting and early warning capabilities and weak emergency management, combined with the needs of emergency dispatch, emergency rescue and disaster relief in the actual process of urban flood control, a flood control decision support method, electronic equipment, storage media and system are proposed.
