The Three Gorges Dam
They built a dam to prevent flooding and saved lives.
Yes, they can both prevent and cause flooding. If you put a dam in a river, it can flood the area and create a lake.
the dam has increased the annual flooding of the nile river
A dam controls flooding by regulating water flow in rivers and reservoirs, storing excess water during heavy rainfall and releasing it gradually to prevent downstream flooding. However, if a dam is poorly managed or experiences structural failure, it can cause flooding by releasing too much water suddenly. Additionally, if the reservoir behind the dam becomes full, it may lead to controlled releases that can overwhelm downstream areas, resulting in flooding. Proper management and maintenance are crucial to balancing flood control and risk.
A natural barrier made of molten rock as it cools is called a lava dam, formed by solidified lava flows. An artificial barrier built to prevent flooding is called a levee, which is a raised embankment constructed along the banks of rivers or lakes to contain or divert floodwaters.
