This study investigated the effectiveness of nature-based solutions (NBSs) as a resilient strategy for mitigating urban flood risks in developing hot arid country. The research method included following steps: (a) performing hazard risk assessment Fifth Settlement district New Cairo, Egypt, (b) selecting best-fit NBSs, and (c) performance assessment. process started with analysis using hydrological data, topographical maps, planning, land use addition to history storm events. step defined areas located depth zones categorized their level. Exposure considered number characteristics population buildings exposed hazards. Vulnerability determined vulnerable populations risk. result this indicated that there were 2000 distributed almost twenty neighborhood facing high One these 72 building units, including residential, public, services buildings, was selected test potential integrating NBSs flood-resilient planning disaster preparedness. selection based on weighted-average sum matrix considering climatic contextual suitability applicability. As final step, numerical simulation models helped assess efficiency stormwater runoff reduction percentage volume capture goal. Five tested each NBS individually. Rain gardens achieved highest percentage, while green roofs performed least effectively, rates 43.6% 9.9%, respectively. Two more developed evaluate when implemented combination compared base case no NBSs. Permeable paving demonstrated capture. applying combined measures over 54.1% total site area able 8% than required Consequently, underscores necessity adopting tailored integrated approaches mitigation. necessitates testing under site-specific conditions future climate projections.
