Problems solved by technology

Therefore, urban construction needs to take the waterlogging risk into consideration, but because the geographical conditions of different geographical locations in the same city are different, and many waterlogging risk predictions do not take into account the geographical conditions of each geographical location in the city, so Prediction flaws

Abstract

The invention provides a Waterlogging risk prediction method and system. The Waterlogging risk prediction method comprises the following steps: 1, dividing a to-be-planned area into a plurality of runoff cells; 2, simulating surface runoff of each runoff plot under different rainfall conditions of the to-be-planned area through an SCS-CN model; 3, simulating the surface runoff of each runoff plotunder the condition of the designed rainstorm recurrence period of the rainwater pipe duct of the to-be-planned area through an SCS-CN model, and taking the surface runoff as the displaceable water amount of the corresponding runoff plot; 4, calculating the difference between the surface runoff of each runoff plot under different rainfall conditions of the to-be-planned area and the displaceable water volume of each runoff plot under the condition of the designed rainstorm recurrence period of the rainwater pipe duct of the to-be-planned area; and step 5, predicting the waterlogging risk of each runoff plot according to the difference value, and providing a scientific basis for reducing the waterlogging risk and updating a construction plan.

Description

technical field [0001] The invention relates to the technical field of waterlogging risk prediction, in particular to a waterlogging risk prediction method and system thereof. Background technique [0002] The phenomenon of urban waterlogging exists in most cities in my country, especially in coastal areas, which are often caused by short-term heavy rainfall such as typhoons and heavy rains. Urban waterlogging not only affects the daily life and travel traffic of urban residents, but also brings economic losses and endangers the lives of the people in severe cases. Therefore, urban construction needs to take the waterlogging risk into consideration, but because the geographical conditions of different geographical locations in the same city are different, and many waterlogging risk predictions do not take into account the geographical conditions of each geographical location in the city, so There is a prediction flaw. Contents of the invention [0003] The purpose of the...
