Abstract

Participants included irrigation water providers,state and federal water-related agencies, consultants, academics and scientists. Anindependent expert facilitated the three workshops. A listing of workshop participants ispresented in Appendix B.Feedback on the technical aspects of the project was complied and considered throughoutthe process. Independent national experts participated in all three workshops. In addition,three international experts participated in the final workshop held in Melbourne. Their rolewas to make sure the proposed process was inclusive, critically reviewed and robust. Theymaintained their independence with regard to science and organisation affiliations.As a result of the workshop findings and existing techniques and knowledge the CSIRO hasalso developed a Technical Manual for Assessing Hotspots in Channel and Piped IrrigationSystems.This document outlines the process by which the Technical Manual for Assessing Hotspotsin Channel and Piped Irrigation Systems was developed by the Commonwealth Scientificand Industrial Research Organisation (CSIRO), for the Irrigation Infrastructure HotspotsAssessment project (the Hotspots project) under the 'Sustainable Rural Water Use andInfrastructure' element of the Australian Government 'Water for the Future' program.The objective of the Hotspots project is to identify areas in an irrigation supply system wherelocalised significant water losses are occurring, through evaporation, seepage, leakage andoperational components, and to quantify the extent of those losses. These water losses arecategorised as 'real' and 'apparent'.The real water loss is water lost through evaporation or by seepage into a saline water table.Once this water is lost it cannot be directly recovered or used for beneficial purposes withinthe irrigation system.Apparent water loss is the volume of water that moves from one system to another andcould become available for beneficial use. However, the first opportunity for beneficial use islost.This document describes the series of workshops that were organised by the CSIRO, incollaboration with the International Centre for Water for Food Security at Charles SturtUniversity, and how they informed the development of the Technical Manual for AssessingHotspots in Channel and Piped Irrigation Systems.Prior to the workshops, four discussion papers were prepared and distributed to seek inputfrom participants. An independent technical writer compiled written feedback on the papers.This feedback is presented in Appendix A.Three workshops were held, in Sydney, Adelaide, and Melbourne, to facilitate furtherconsultation with key water practitioners.
