A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A ...

May 21, 2024 · Most modern dams are of two basic types: masonry (concrete) gravity designs and embankment (earthfill or rockfill) designs. Masonry dams are typically used to block streams running through relatively narrow gorges, as in mountainous terrain; although the structures may be very high, the total amount of material required for such sites is limited.
Dams produce hydroelectric power and the reservoirs behind dams store water supplies for the long haul. Infrastructure, such as levees and canals, channel water to our homes and fields, and keep...
