Proceeding of the Joint International Symposium on Deformatuon Monitoring. 2-4 November, 2011. Hong Kong. China. Report. Goulburn-Murray Water, Australia's largest irrigation authority, manages fifteen storages for irrigation and domestic purposes. Each of these storages is monitored for deformation twice yearly, at the beginning and end of the irrigation cycle. Theoretically this invokes maximum and minimum levels in the storages, consistent with changes in operating procedures and variances in soil mechanics. The methods of surveillance of the storages has changed in the last ten years in accordance with improvements in surveying technology, updated calibrations of the storages and improved methods of evaluating results. The need to increase the audit of information on storages has been at the forefront of increased expenditure in this area. The traditional method of measuring deformation or movement at various storages using a theodolite and level has in most cases been surpassed by use of GPS and electronic level or Total Station and electronic level. This is not to demean the previous methods which have produced very good results, but allows more points to be observed with greater accuracy in more remote positions. In addition, during the last ten years the storages have been at historically low levels, exposing upstream monitoring points, thus providing a true deformation model. Newer techniques have been employed to survey these points. This paper explores some of the history of deformation surveys, the use of newer technology, the importance of information for storages and the management and evaluation of data. It incorporates the survey aspect and the dam engineering reports and evaluations. Input in this paper will come from a number of sources, experience surveyors and dam safety engineers. Finally discussions will be presented on improvements that can be made to existing procedures in order to maximise results in the future as increased pressure is put on organisations to manage not only the water reserves but the safety of these resources.
