AUSTRALIA’S LONG-TERM INTERVENTION MONITORING PROJECT – A MAJOR DATA RESOURCE FOR TESTING FLOW-ECOLOGY HYPOTHESES
The development of generalizable flow-ecology relationships has been held back by the inconsistency of data sets over large spatial scales. As part of the Australian Government’s Murray Darling Basin Plan, the Commonwealth Environmental Water Office has funded a five year program – the Long-Term Intervention Monitoring Project - to collect data on ecological responses to environmental flows across the Murray Darling Basin. Data collection is being undertaken in seven ‘selected areas’, with data also being analysed across areas in large-scale analyses. The focus of monitoring on the ‘intervention’ of environmental flow events yields dividends for flow-ecology science and management. For example, combining field data on spawning of golden perch (Macquaria ambigua), with the outputs of 2-dimensional hydraulic models, we now have a strong understanding of the conditions needed to induce spawning in this iconic fish species. Results are being used to inform water delivery decisions via adaptive management, helping managers to extract maximal value from the limited environmental water available. Longer-term, the project is providing a wealth of targeted empirical data to help us better understand ecological responses to flow restoration in Australia’s most flow-impacted river system.

Presenters/Authors
Angus Webb
(), The University of Melbourne, angus.webb@unimelb.edu.au;
Dr Angus Webb is a Senior Lecturer in Environmental Hydrology and Water Resources at the University of Melbourne, Australia. He originally trained as a marine ecologist before moving into the study and restoration of large-scale environmental problems in freshwater systems. Much of his research centers on improving the use of the existing knowledge and data for such problems. To this end he has developed innovative approaches to synthesizing information from the literature, eliciting knowledge from experts, and analyzing large-scale data sets. He is heavily involved in the monitoring and evaluation of ecological outcomes from the Murray-Darling Basin Plan environmental watering, leading the program for the Goulburn River, Victoria, and advising on data analysis at the basin scale. Angus is currently a co-editing a major new text book on environmental flows science and management. He was awarded the 2013 prize for Building Knowledge in Waterway Management by the River Basin Management Society, and the 2012 Australian Society for Limnology Early Career Achievement Award.
