Abstract: Urban flooding has emerged as a recurrent disaster threatening infrastructure, economy, and human lives, especially in densely populated cities. Rapid urbanization, inadequate drainage, and climate-induced extreme rainfall events have aggravated the frequency and severity of floods. Hydraulic structures such as detention basins, retention ponds, underground storage systems, and diversion channels play a pivotal role in mitigating urban floods. This paper explores the design principles, performance evaluation, and integration of hydraulic structures into urban stormwater management systems. Through case studies and tabulated comparisons, we analyze how these engineering interventions enhance resilience and minimize the impact of urban flood events.
Keywords: Urban flooding, hydraulic structures, detention basin, retention pond, flood mitigation, stormwater management, resilience
