Dams are part of human achievements that induce great benefits for society but also bear a potential risk to people, property and the natural environment. The risk of a dam rupture is extremely low and diffi cult to quantify accurately. The aim of Dam surveillance (ICOLD Bulletin 158), is to help reduce these risks by early detection of an undesirable event.

The objective of dam surveillance is to make a precise and timely diagnosis of the behavior of dams, in order to prevent undesirable consequences. Both the monitoring system and surveillance program has to be designed and should be able to detect any abnormal behaviour. Dam surveillance (ICOLD Bulletin 158), emphasizes the following aspects:

Routine visual inspection

Special inspection

Checking and testing of Hydro-electromechanical equipment

Monitoring parameters and devices

Automation

Maintenance of ageing monitoring systems

Re-instrumentation of existing dams

Recent developments

Data management

Dam documentation management

Assessment of dam condition and behaviour

Assessment of routine dam safety monitoring programme

Prioritization of maintenance, remedial and upgrading works.

the Commission Internationale des Grands Barrages (CIGB) / International Commission on Large Dams (ICOLD) is a non-governmental International Organization which provides a forum for the exchange of knowledge and experience in dam engineering.

The Organization leads the profession in ensuring that dams are built safely, efficiently, economically, and without detrimental effects on the environment. Its original aim was to encourage advances in the planning, design, construction, operation, and maintenance of large dams and their associated civil works, by collecting and disseminating relevant information and by studying related technical questions.

Since the late sixties, focus was put on subjects of current concern such as dam safety, monitoring of performance, reanalysis of older dams and spillways, effects of ageing and environmental impact. More recently, new subjects include cost studies at the planning and construction stages, harnessing international rivers, information for the public at large, and financing.
