A gravity dam is an engineering structure that by its own weight resists the forces imposed with a desired factor of safety. Gravity dams are designed so that every dam section is stable, independent of any other dam section.[1][2]

The most common classification of gravity dams is by the materials composing the structure:

  • Composite dams are a combination of concrete and embankment dams. Construction materials of composite dams are the same used for concrete and embankment dams. Folsom Dam is a composite dam.

Gravity dams can be classified by plan (shape):

Gravity dams can be classified with respect to their structural height:

  • Low, up to 100 feet.
  • Medium high, between 100 and 300 feet.
  • High, over 300 feet.
