Climate Change Effect on The South Iraq Stormwater Network

The important issue that municipalities face is the process of urban flood control and monitoring due to the damage these floods cause to infrastructure. To reduce potential climate change risks, this study aimed to develop a decision to determine the efficiency of stormwater networks in Basra, Iraq. Based on the data obtained from 1979 to 2018, the Storm Water Management Model (SWMM) program was used to simulate the stormwater network in Basra and use this data to predict the annual precipitation in the future until 2099 using the Statistical downscaling Model (SDSM). The results indicate a future rise of (0.14 to 1.07) °C as a maximum temperature. As a result of climate change, the intensity of rain is expected to increase beyond the network capacity to reach 21.5 mm/hr. The network's design capacity is 11.5 mm/hr., leading to 34% of manholes overflow.
