Dams may be built to provide water for irrigation or town water supply, control the amount of water in rivers or to provide hydroelectric power.
Earth dams are constructed as a simple homogeneous embankment of well-compacted earth, sometimes with a watertight concrete core or upstream face, or sometimes with a hydraulic fill to produce a watertight core.
A type of temporary earth dam occasionally used in high lattitudes is the frozen-core dam, in which a coolant is circulated through pipes inside the dam to maintain a watertight region of permafrost within it.

 dam. The Columbia Encyclopedia, Sixth Edition. 2001-05
Single-arch dams are curved upstream and are usually constructed in narrow canyons or gorges where the rocky side walls are strong enough to withstand the tremendous lateral thrust of the dam that is caused by the pressure of the water.
Dams may also be constructed with roller-compacted concrete, in which thin layers of concrete are compacted as if they were earth layers; this produces a far stronger dam, without the need for full forms.
