Multi-scale, two-phase flow in complex coal seam systems. Australia is the world’s leading coal exporter and a large consumer of coal. This project aims to fill key knowledge gaps that underpin the challenge facing the coal industry and environmental agencies in assessing the impact of coal mining on the surrounding environment, in particular, adjacent river and groundwater systems.
Defining and controlling seawater intrusion in threatened coastal aquifers. This project aims to improve knowledge of coastal aquifer processes and management practices in order to increase the security of highly vulnerable freshwater. In particular, it aims to address critical barriers to the regional-scale investigation of coastal aquifers, including island lenses – the most vulnerable freshwater resources on earth. Threats to coastal aquifers are intensifying globally, and key knowledge gaps ....Defining and controlling seawater intrusion in threatened coastal aquifers. This project aims to improve knowledge of coastal aquifer processes and management practices in order to increase the security of highly vulnerable freshwater. In particular, it aims to address critical barriers to the regional-scale investigation of coastal aquifers, including island lenses – the most vulnerable freshwater resources on earth. Threats to coastal aquifers are intensifying globally, and key knowledge gaps prevail in our current understanding and representation of transient, regional-scale seawater intrusion. The project plans to use coastal aquifer case studies from Australia and overseas to evaluate seawater intrusion reversibility, intermittent pumping effects, offshore aquifer processes, and management approaches. The project may improve coastal aquifer practices globally by unravelling the driving forces of transient seawater intrusion and developing new seawater intrusion models.Read moreRead less
A novel and theoretically consistent method for correcting systematic errors in earth observation data and earth system model results. For a correct interpretation of satellite-based earth observation data and/or Earth system model results, it is very important that these data are free of systematic errors, commonly referred to as bias. It is well known that both these data sources are prone to a significant bias, which is currently neglected in many environmental impact and prediction studies. ....A novel and theoretically consistent method for correcting systematic errors in earth observation data and earth system model results. For a correct interpretation of satellite-based earth observation data and/or Earth system model results, it is very important that these data are free of systematic errors, commonly referred to as bias. It is well known that both these data sources are prone to a significant bias, which is currently neglected in many environmental impact and prediction studies. This project will present a method to develop models for these biases. A state update technique, the Ensemble Kalman Filter, will be adapted to correctly take into account bias in the merging of the two data sources. The project outcomes will be of high importance for long-term environmental studies, since these strongly rely on physically-based models and remote sensing data.Read moreRead less
Exploring water worlds for ecohydrologic modelling of ephemeral catchments. This project aims to identify and quantify the key processes driving the generation of streamflow in ephemeral catchments with different rainfall regimes, topography, geology, and two contrasting land uses. Four ephemeral catchments in south-western Victoria will be used as a case study to identify how these catchments store and release water. Particular focus will be directed to understanding the roles of groundwater an ....Exploring water worlds for ecohydrologic modelling of ephemeral catchments. This project aims to identify and quantify the key processes driving the generation of streamflow in ephemeral catchments with different rainfall regimes, topography, geology, and two contrasting land uses. Four ephemeral catchments in south-western Victoria will be used as a case study to identify how these catchments store and release water. Particular focus will be directed to understanding the roles of groundwater and surface runoff in supplying the streams when they flow, and how rainfall is partitioned between tree water use, groundwater recharge, and streamflow. The outcomes from experimental observations will be used to improve current hydrological models to support land and water management.Read moreRead less
