2013 – Deformation surveying of dams in New Zealand

Steve Currie

The dam surveillance industry relies on deformation survey data to assist in understanding and monitoring dam performance. My paper presents an overview of New Zealand dam deformation surveying. The fundamentals and best practice of deformation surveying are discussed, along with accuracies achieved and developments in automated measurements in real time. The key to achieving high accuracy in the results is using precise well calibrated survey instruments, many redundant measurements, quality survey marks and rigorous computational routines.
