How Does Extreme Rainfall Cause Dam Failures? Have you ever wondered how extreme rainfall can lead to dam failures and cause devastating floods? In this informative video, we'll explain the key ways heavy rain impacts dam safety and the potential consequences of such failures. We'll start by discussing the main process called overtopping, where rising water levels spill over the top of the dam, often eroding the structure and causing it to weaken or collapse. You'll learn how dams are equipped with spillways designed to release excess water safely, but these can be overwhelmed or blocked during intense storms, increasing the risk of failure. The video also covers internal erosion, known as piping, where water seeps through cracks or weak spots inside the dam, gradually washing away material and creating tunnels that compromise stability. Additionally, we'll explore how heavy rain can trigger landslides or debris flows that block rivers and form natural dams, which may also fail suddenly and lead to flash floods. The consequences of dam failure can be severe, including destruction of homes, communities, and even loss of life, especially in older or poorly maintained structures near populated areas. Proper management of heavy rains and regular dam maintenance are essential to prevent these disasters. Join us to understand how extreme weather impacts dams and what measures can be taken to improve safety.
