Respuesta :
With depth, the dam's water storage pressure rises. Hence, dams have a wider bottom in order to accommodate the rising water pressure.
Give a brief account on dam.
The flow of surface water or subsurface streams can be stopped or restricted by a dam. Dams produce reservoirs that serve as a source of water for navigation, aquaculture, irrigation, human consumption, industrial use, and flood control. Electricity is frequently produced by combining hydropower and dams. A dam can also be used to gather or store water that can be distributed equitably among many sites. While other structures, like floodgates or levees, are used to control or limit water flow into particular geographical zones, dams typically serve the primary purpose of retaining water. The Jawa Dam in Jordan is the oldest known dam and dates back to 3,000 BC.
Enlisted below are few purposes of dam :
- Water supply: Residental, commercial, and mining areas are supplied with sufficient quantities of high-quality freshwater from the dam's reservoirs.
- Irrigation: In many nations, water stored behind dams is used to irrigate agriculture.
- Dams are necessary for the hydroelectric power plants' electrical generation.
- Flood control: For thousands of years, humanity have constructed dams to help prevent catastrophic floods. Loss of life and property is less likely because to it. Flood control dams hold floodwaters until they can be released into the river below the dam, stored, or diverted for use elsewhere.
