What are the 5 factors that increase the risk of flooding?

Five factors that increase the risk of flooding include heavy rainfall, which can overwhelm drainage systems; rapid snowmelt, leading to increased water flow; urbanization, which reduces natural absorption and increases runoff; deforestation, which decreases soil stability and water retention; and the presence of river dams, which can fail or be overwhelmed during extreme weather events. Additionally, rising sea levels due to climate change can exacerbate coastal flooding risks.
