Scientific Results

This catalogue is obtained by conducting a systematic literature review of scientific studies and reviews related to monitoring, forecasting, and simulating the inland water cycle. The analysis maps scientific expertise across research groups and classifies findings by the type of inland water studied, application focus, and geographical scope. A gap analysis will identify missing research areas and assess their relevance to policymaking.

publications-3782 article 1983 Plackett, R. L. and Plackett, R. L. Karl Pearson and the Chi-squared Test International Statistical Review 10.2307/1402731 Summary Pearson's paper of 1900 introduced what subsequently became known as the chi-squared test of goodness of fit. The terminology and allusions of 80 years ago create a barrier for the modern reader, who finds that the interpretation of Pearson's test procedure and the assessment of what he achieved are less than straightforward, notwithstanding the technical advances made since then. An attempt is made here to surmount these difficulties by exploring Pearson's relevant activities during the first decade of his statistical career, and by describing the work by his contemporaries and predecessors which seem to have influenced his approach to the problem. Not all the questions are answered, and others remain for further study.

We are used to data coming from instruments; now, however, we experience data everywhere. Combine that with customer-use data through automated meter reading or advanced metering infrastructure and a better-informed public that provides real-time feedback with social media, and you get data overload. The question facing the industry is how to use the data it receives.

publications-3788 article 2009 Giustolisi, Orazio and Giustolisi, Orazio and Berardi, Luigi and Berardi, Luigi Prioritizing pipe replacement: from multiobjective genetic algorithms to operational decision support. Journal of Water Resources Planning and Management 10.1061/(asce)0733-9496(2009)135:6(484) Deterioration of water distribution systems and the optimal allocation of limited funds for their rehabilitation represent crucial challenges for water utility managers. Decision makers should be provided with a set of β€_x009c_informedβ€_x009d_ solutions to select the best rehabilitation plan with regard to available resources and management strategies. In a risk-based scenario, such an approach should result in an element-wise prioritization scheme based on individual pipe rehabilitation/replacement effectiveness. This manuscript describes a framework for devising a short-term decision support tool for pipe replacement. The approach allows for the introduction of economic, technical, and management rationales as separate objectives to produce a pipe-wise prioritization scheme which is achieved by ranking pipes selected during a multiobjective (MO) evolutionary optimization of replacement scenarios. Such a procedure helps overcome the doubts in choosing among the solutions obtained by MO evolutionary optimization due to...

Water security through scarcity pricing and reverse osmosis: A system dynamics approach Journal of Cleaner Production 10.1016/j.jclepro.2014.05.009 Water supply and demand planning is often conducted independently of social and economic strategies. There are presently no comprehensive life-cycle approaches to modelling urban water balances that incorporate economic feedbacks, such as tariff adjustment, which can in turn create a financing capacity for investment responses to low reservoir levels. This paper addresses this gap, and presents a system dynamics model that augments the usual water utility representation of the physical linkages of water grids, by adding inter-connected feedback loops in tariff structures, demand levels and financing capacity. The model, applied in the south-east Queensland region in Australia, enables simulation of alternatives and analysis of stocks and flows around a grid or portfolio of bulk supplies including an increasing proportion of rain-independent desalination plants. Such rain-independent water production plants complement the rain-dependent sources in the region and can potentially offer indefinite water security at a price. The study also shows how an alternative temporary drought pricing regime not only defers costly bulk supply infrastructure but actually generates greater price stability than traditional pricing approaches. The model has implications for water supply planners seeking to pro-actively plan, justify and finance portfolios of rain-dependent and rain-independent bulk water supply infrastructure. Interestingly, the modelling showed that a temporary drought pricing regime not only lowers the frequency and severity of water insecurity events but also reduces the long-run marginal cost of water supply for the region when compared to traditional reactive planning approaches that focus on restrictions to affect demand in scarcity periods.
publications-3790 article 2011 Willis, Rachelle McDonald and Willis, Rachelle McDonald and Stewart, Rodney Anthony and Stewart, Rodney Anthony and Williams, Philip L. and Williams, Philip and Hacker, Charles Hilton and Hacker, Charles Hilton and Emmonds, S.

Residential potable and recycled water end uses in a dual reticulated supply system Desalination 10.1016/j.desal.2011.01.022 The need to understand, model and predict urban water consumption is paramount, particularly with urban densities increasing throughout the world. Specifically, it is vital to determine potable water savings, daily demand patterns and actual end use water consumption experienced in diversified water supply schemes in order to verify planning estimates and justify the future application of such schemes. This paper details the results of a mixed methods (quantitative and qualitative) end use investigation, pre- and post-commissioning of recycled water, in a dual reticulated supply scheme in the master planned Pimpama Coomera region, Gold Coast, Australia. Recycled water, supplied for irrigation and toilet flushing, accounted for 59.1 L/p/d or 32.2\% of total consumption post-commissioning, with irrigation being 28.9 L/p/d or 15.7\%. Furthermore, developed end use diurnal patterns demonstrate the unique daily demand consumption within the region and significant reductions in peak potable water demand when compared with single reticulated supply areas. The paper concludes with discussions of implications for better informed water services infrastructure planning activities.
