A nonstructural flood prevention measure for mitigating urban inundation impacts along with river flooding effects.

摘要: In recent decades, urban developments along rivers have experienced high flooding risks, elevated by increasing urbanization. Due to the expansion of areas, flood mitigation strategies must rely on nonstructural management policies. This study evaluated impacts pluvial floods considering fluvial effects through field surveys and numerical model simulations. Nonstructural protection measures are provided establishing warning water levels based variant scenario The results reveal that aggravated drainage system overflow induced river is significant when effects. As a result, current systems failed meet designed standards, indicating need produce potential inundation maps establish levels. To prevent main evacuation route each settlement from being blocked due flooding, proposed support timely effective evacuations. Public community centers schools in noninundation areas near settlements were identified as possible shelters maps. We conclude although riverside without dike could sustain natural environments landscapes, they incorporate measures. At same time, it be considered may reduce capacity.
