Dam
A dam is a structure built across a river or waterway to hold back and control the flow of water. It creates a reservoir or lake, which can be used for purposes such as generating electricity, supplying water for irrigation and drinking, controlling floods, and providing recreational opportunities. Dams are designed to withstand the pressure of large volumes of water and often incorporate spillways to release excess water safely. They play a vital role in water resource management, but their construction can impact ecosystems and local communities, making careful planning essential.
