Floods are one of the most widespread and destructive natural disasters, often occurring suddenly due to heavy rainfall or dam failures, and can cause extensive damage and loss of life in populated urban areas. The effects of floods include destruction of homes and infrastructure, loss of lives, disease outbreaks, and damage to farmlands. Proper preparation and prevention measures are needed to reduce risks from potential flooding.
