Measuring the effect of land use on changes to fluxes
Research into deep drainage, evapotranspiration and recharge is allowing better understanding of the effects of land use on shared water resources. More Information
Hydrodynamics and Modelling of Complex Groundwater Systems
Assessing spatial and temporal recharge distributions using regularised parameter estimation of a groundwater flow model: A case study of Uley South Basin (South Australia)
This project focuses on enhancing spatial and temporal recharge estimates by using state-of-the-art groundwater model calibration techniques. Specifically, we aim to address the question: “to what extent can we enhance our understanding of recharge through the calibration of a groundwater flow model?” More Information
Parameter and predictive outcomes of model simplification and calibration
This work presents a systematic analysis of the outcomes of model simplification and calibration. The effect of simplified model calibration upon model predictive performance is shown to be highly prediction-specific. The same simplification and calibration approach may improve predictive performance for some predictions whilst actually degrading that for others. More Information
Surface Water – Groundwater Interactions
Determining groundwater ages in heterogeneous environments.
Quantifying the age of groundwater in complex geological environments remains a challenge for groundwater scientists. We are investigating the limits of current methods and proposing new methods for quantifying these ages. More Information
Determining groundwater discharge and chemistry from multiple aquifers by longitudinal river sampling
This project establishes a new method for estimating the location(s) of groundwater discharge to a river and its chemistry by sampling river water. This method may be particularly useful in remote areas where access to groundwater is limited or impossible, drilling is not an option due to budget constraints, and to identify contamination sources.

Transient infiltration from ephemeral streams
This project highlights and quantifies the importance of transient infiltration rates at the flow onset in ephemeral streams. More Information
Groundwater–Vegetation–Atmosphere Interactions
Effects of land use change on groundwater and surface water resources
This PhD research investigated the impact of a young tree plantation on water quality and quantity at a study site in southwest Victoria. The plantation was found to reduce the amount of water leaving the catchment as the trees use more water than an adjacent farm. More Information
Integrating Socioeconomics, Policy and Decision Support
Preliminary assessment of conjunctive use opportunities in the Murray Darling Basin
The Murray-Darling Basin has a long history of irrigated agriculture using both surface water and groundwater resources. However, with climate change and the recognition that the environment needs a larger share of the water to maintain its function, irrigated agriculture is under pressure to maintain production and economic viability, with reduced and a sometimes highly variable water source.
