A method for forecasting urban waterlogging, electronic equipment and storage medium

Abstract

The invention discloses a method for forecasting urban waterlogging, electronic equipment and a storage medium. The method comprises: establishing an urban waterlogging model; developing design rainfall with different recurrence periods according to the local rainstorm intensity formula and Chicago rainfall pattern; Input it to the urban waterlogging model for calculation, and obtain the urban waterlogging data at different times along with the rainfall process and store it in the database; obtain the urban forecast rainfall, query the design rainfall of the corresponding return period in the database according to the urban forecast rainfall, and obtain the urban forecast Urban waterlogging data corresponding to rainfall; waterlogging risk forecasting based on urban waterlogging data corresponding to urban forecast rainfall. This method can compare the design rainfall in the database with the design rainfall in the database to determine the corresponding urban waterlogging data based on the rainfall forecast information released in advance by the Urban Meteorological Bureau. efficiency and precision.

Description

technical field [0001] The invention relates to the technical field of urban waterlogging risk forecasting, in particular to an urban waterlogging forecasting method, electronic equipment and a storage medium. Background technique [0002] With the acceleration of urbanization, the increase of surface hardening rate, the weakening of urban water storage and stagnant capacity, coupled with the frequent occurrence of extreme rainstorms in the flood season, every year in the flood season, "seeing the sea" landscapes appear in various places, which greatly affects urban travel and life and production, and even Cause waterlogging disaster, endanger life and property safety. How to reduce the impact of urban waterlogging, forecast urban waterlogging risk in advance, locate waterlogging location, quantify waterlogging depth, area, time and other information, and take proactive measures to avoid risks are crucial to improving urban water security and ensuring safe and orderly operat...

Problems solved by technology

However, the occurrence of urban waterlogging is the result of the influence of multiple factors, including rainfall module, surface production and confluence module, pipe network transfer module, downstream river and lake water body module, etc. At present, there are mature urban waterlogging calculation models, but only meet the offline calculation efficiency Requirements, the timeliness of online drive calculation is low, and cannot meet the time requirements for urban waterlogging forecast and risk-avoidance disposal
