This project aims to develop an integrated irrigation scheduling, benchmarking and forecasting capability delivered through a water ordering portal that is used by most Australian irrigation farmers and many farmers internationally. Ensuring adoption is critical and this will be facilitated through integration into the existing water ordering system. Expected outcomes include improved ability to manage irrigation water through better use of existing weather observations and forecasts, irrigation data, and satellite observations to inform farmer decisions. This is expected to result in improvement in water productivity, leading to economic benefit and an improved ability to meet growing global food demands.Read moreRead less
A microbiological risk assessment model for the use of reclaimed water in irrigated horticulture. The volume of reclaimed water used in Australia is increasing. A major use of reclaimed water is irrigation of horticultural crops. There are considerable associated risks including contamination of soil and plants and accidental ingestion of harmful pathogens. Whilst research on many risks has been conducted, there are knowledge gaps and information is not readily available to managers. The centr ....A microbiological risk assessment model for the use of reclaimed water in irrigated horticulture. The volume of reclaimed water used in Australia is increasing. A major use of reclaimed water is irrigation of horticultural crops. There are considerable associated risks including contamination of soil and plants and accidental ingestion of harmful pathogens. Whilst research on many risks has been conducted, there are knowledge gaps and information is not readily available to managers. The central aim of this project will be to develop a new, comprehensive mathematical risk assessment model able to simulate different irrigation and horticultural scenarios. The primary output will be a user-friendly environmental decision support system incorporating the newly developed model.Read moreRead less
Optimum design of hydraulic structures in rural and urban Australia: dealing with floods and droughts. Australia's long-term forecast suggests the occurrence of longer and more frequent droughts, and more intense flood events. The project will study the fundamental hydrodynamic processes in hydraulic structures and aims to develop new innovative designs derived from process based approach for optimum operation in rural and urban Australia.

Summary
Fundamental aspects of vertical and horizontal consolidation in a multi-layered soil system. Land reclamation is a multi-billion dollar industry that is most often carried out in coastal regions by reclaiming seabed foundations of marine clay using dredged waste. This project will develop an analytical framework for predicting the rate of settlements in the resulting multi-layer system which will incorporate a variety of factors known to directly influence the rate of consolidation. After valida ....Fundamental aspects of vertical and horizontal consolidation in a multi-layered soil system. Land reclamation is a multi-billion dollar industry that is most often carried out in coastal regions by reclaiming seabed foundations of marine clay using dredged waste. This project will develop an analytical framework for predicting the rate of settlements in the resulting multi-layer system which will incorporate a variety of factors known to directly influence the rate of consolidation. After validation using experimental data and numerical simulations, the proposed analytical model can be used to mimic soil behaviour more closely than traditional models, thereby leading to more realistic settlement predictions.Read moreRead less
A new strategy for design flood estimation in a nonstationary climate. Evidence suggests that global warming will result in an increase in the frequency and/or magnitude of heavy rainfall, leading to flooding with potentially devastating consequences. This study provides a renewed focus on design flood estimation that takes into account a changing climate where assumptions of stationarity are no longer tenable.
