Evaluating the Effectiveness of Low Impact Development Practices against Climate Induced Extreme Floods

Short but extreme flooding events have been frequent and severe globally due to climate change urbanization in recent years. Similarly, researchers, scientists, water managers are suggesting the application of sustainable flood management strategies such as Low Impact Development (LID) mitigate impacts events. However, most these primarily evaluated using historical precipitation events, which may not accurately represent impact climate-induced projected become more extreme. In this context, study assesses effectiveness LIDs combating change-induced The North American Regional Climate Change Assessment Program (NARCCAP) model was applied quantify magnitude future storm depths, expected increase change. Personal Computer Storm Water Management Model (PCSWMM) used develop a rainfall-runoff simulation assess three LID techniques (Permeable Pavement, Green Roof, Bio-Retention Cell) reducing surface runoff under various scenarios. results revealed that scenarios design depths by up 104%. peak discharge, total volume were found 37.72% 88.73%, respectively scenario. Furthermore, demonstrated applying decreases offering viable solution tackle induced illustrated performance permeable pavement superior discharge 28.57%. green roofs bioretention cells reduced 19.93% 14.25%, respectively.
