At least twice a year : pre monsoon and post monsoon
Examination of general health of the dam and appurtenant works
Preparedness of dam and hydro mechanical structures for handling expected floods
Comprehensive Dam Safety Evaluation
Once in a 10 year
More comprehensive examination
Multi-disciplinary team for holistic view
May order additional field and laboratory investigations as well as numerical simulations
CDSO has prepared a number of guidelines on dam safety and circulated these to the State Governments and other organisations for implementation.
CDSO (in 1990) compiled an National Register of Large Dams which is being updated continuously.
CDSO is regularly imparting trainings to the engineers of CWC as well as State Governments to enhance their knowledge and skills in the field of Dam Safety.
Assistance by CDSO is rendered only on specific request from State Governments. Apparently, it is not practical for such a dam safety service at the Centre to cater to the needs of all the dams in the country.
