Method for simulating urban waterlogging depth based on SWMM of pipe network and road dual system

Abstract

The invention discloses a method for simulating urban waterlogging depth based on an SWMM of a pipe network and road dual system. The method comprises the steps of collecting basic data; performing topological structure processing on the basic data; performing attribute addition on the basic data; constructing a pipe network and road dual system; performing model building and simulation; and outputting a waterlogging depth result. On the basis of the SWMM, pipe networks and roads are combined to form the dual system, and the diffuse flow of overflow water on the roads can be simulated, so thatthe two-dimensional road surface flood and waterlogging depth is calculated out, and the defect that the waterlogging depth cannot be calculated by normal-scale hydraulic simulation of the SWMM is overcome.

AI Technical Summary

Benefits of technology

This patented technology allows us to study how city streets become overwatered by heavy rain or snow during winter months when there're no roads nearby. It uses models made through pipes networks and two systems - one with an underground pipeline called a street lining (SWML) and another without any physical connections between them like cables. These simulations help researchers better identify potential sources of future flooding events such as fires caused by falling debris or other factors affecting their safety measures.

Problems solved by technology

The technical issue addressed in this patented text relates to how to accurately evaluate the impact on community sewer systems due to severe rainfall or other factors such as overfilling piles with debris during construction work hours without causing damage.
