What are the advantages and disadvantages of Earth Dam??


 Are usually cheaper than gravity dams if suitable earth for construction is available near the site.

Can be constructed on almost all types of foundations, provided suitable measures of foundation treatment and seepage control are taken.

Can be constructed in a relatively short period.

Are more earthquake-resistant than gravity dams.


Are not suitable for narrow gorges with steep slopes.

 Cannot be constructed in regions with heavy downpour, as the slopes might be washed away. 

Maintenance cost of an earth dam is quite high. It requires constant supervision. 

Fails suddenly without any sign of imminent failure. A sudden failure causes havoc and untold miseries.
