Urban flooding refers to the inundation of urban areas due to heavy rainfall, inadequate drainage systems, and other factors that can cause water to accumulate on streets, buildings, and other urban infrastructure. This can result in property damage, disruption of transportation systems, and even loss of life. Research in this area focuses on understanding the causes and impacts of urban flooding, developing strategies to mitigate its effects, and improving urban planning and infrastructure to reduce vulnerability to flooding in cities. Key research areas include stormwater management, flood risk assessment, urban drainage systems, climate change adaptation, and community resilience to flooding events.
