An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. [1]
The following table lists the largest man-made dams by volume of fill/structure. By general definition, a dam is a barrier that impounds water or underground streams, hence tailings dams are relegated to a separate list.
Nanma Dam is a rockfill dam located in Tochigi prefecture in Japan. The dam is used for flood control and water supply. The catchment area of the dam is 139.3 km 2.The dam impounds about 210 ha of land when full and can store 51000 thousand cubic meters of water.

The tallest embankment dam and second tallest dam in the world is the 300 m (984 ft) Nurek Dam in Tajikistan. The tallest gravity dam is the 285 m (935 ft) high Grande Dixence Dam in Switzerland. The tallest natural dam, the 567 m (1,860 ft) Usoi Dam in Tajikistan, is 262 m (860 ft) taller than the tallest existing man-made one.
Typically, a base or starter dam is constructed, and as it fills with a mixture of tailings and water, it is raised. Material used to raise the dam can include the tailings (if their properties are suitable), earthfill, or rockfill. [7] It is increasingly common for barrier systems such as geomembranes to be incorporated into tailings dams ...
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 ...
