摘要: Abstract With rapid urbanization, rainstorm-induced inundation losses are becoming increasingly severe. Research on urban response to rainstorm patterns can help engineers and governments make appropriate decisions mitigate property losses. This paper introduces a new hydrodynamic model that couples the storm water management (SWMM) shallow (SWM) applies validated Haidian Island case determine patterns. The results show coupled predict well, different would result in increasing peak position coefficients, events become more severe peaks appear sooner. However, times at which occurs do not change. To reasons for differences among patterns, correlations between volume fully-filled pipes ratio were analyzed. Correlation analysis showed significantly related working state of sewer system, indicating higher prior will inundation. conclusion suggests range coefficients China is quite reasonable. provide insights government design planning maintenance.
