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
Checking and testing of Hydro-electromechanical equipment
Monitoring parameters and devices
Maintenance of ageing monitoring systems
Re-instrumentation of existing dams
Dam documentation management
Assessment of dam condition and behaviour
Assessment of routine dam safety monitoring programme
Prioritization of maintenance, remedial and upgrading works.
