Floods: Understanding and Safety

The video tutorial explains floods as natural events where dry land becomes submerged due to excessive water. It highlights the dangers of flooding, such as carrying away objects and causing destruction. The main causes of flooding include heavy rain, overflowing rivers, dam breaks, strong winds, and melting snow. The video describes four types of floods: flash floods, rapid onset floods, slow onset floods, and storm surge flooding. It emphasizes the importance of safety measures before, during, and after floods, such as evacuation, turning off utilities, and staying away from power lines.
