The collection, storage and analysis of information concerning a dam
are a critical part of surveillance activity toward managing the safety of the structure. An important part on handling of this information is the interpretation of data coming from the monitoring. In addition, the use of automatic instrumentation has resulted in large amounts of data requiring analysis and interpretation. The use of decision support system for the on-line checking of dam’s behavior is useful to reduce human time consuming and to request timely human intervention and analysis.
