Presentation Title: Condition assessment of dam surveillance instruments

Abstract: Condition assessment is essential in understanding the performance of dam surveillance instruments. The assessment results can provide critical information on the integrity of measurement data. Desktop review is used to assess the functional condition of the instruments. Site inspections reveal the physical conditions. Different types of instruments require different assessment techniques. The inspection methods for boreholes, standpipes, hydraulic piezometers, vibrating wire transducers and V-Notch weirs are presented.
