Rock-fill dams are embankments of loose rock with either a watertight upstream face of concrete slabs or timber or a watertight core.
Earth dams, also called earthen and earth-fill dams, are constructed as a simple homogeneous embankment of well-compacted earth, sometimes with a watertight concrete or clay 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 latitudes 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.

One of the first dams built was the Dujiangyan dam on the Minjiang River (Sichuan) or Min River, a tributary of the Yangtze River, in what is now the province of Sichuan.
The dam will not overturn provided that the moment (physics) around the turning point, caused by the water pressure is smaller than the moment caused by the weight of the dam.
If the upstream face is vertical the entire weight of the dam must be carried to the foundation by gravity, while the distribution of the normal Fluid pressure#Hydrostatic pressure between vertical cantilever and arch action will depend upon the stiffness of the dam in a vertical and horizontal direction.
