Planning a performance monitoring program is an essential
component of successful dam construction and operation.
Dam monitoring is recommended to ensure the safety
of a dam and to control its trend.

DAM MONITORING BENEFITS
•   Evaluate the initial conditions at dam site
•   Safety during construction stages
•   Safety during initial filling and frawdown,

                 the readings converting them into engineering units in order to add them to its SQL database.
                 The readings are then available in the form of charts or tables through the “Galemys”
                 application. The entire process is automated so that current data are available 24 hours a day,
