Earthen Dams

Earthen Dams or Earth dams are the dams which are built of compacted soil or rock fragments.

Characteristics of Earthen Dams

  • They are designed as gravity dams.
  • They are much more massive than concrete gravity dams.
  • Thus they require larger amount of materials.
  • Many earth dams contain more than 5 billion cubic meter of compacted soil.
  • They do not need form work which saves money.
  • The unit cost of compacted fill is much less as compared to concrete dams, so their total cost is usually less
