This research project will develop emissions models for commercial vehicles that are capable of modelling changes in driver behaviour. Second by second emissions data from certification tests will be disaggregated into their component phases of acceleration, cruise, deceleration and idle. The emissions characteristics of these phases will be established and analysed to produce empirical models of emissions per unit time versus mode of operation. These models will then be able to describe the changes in emission characteristics under different commercial vehicle operating modes for a range of commercial vehicle types.Read moreRead less

Qualitative and quantitative modelling of hydraulic fracturing of brittle materials. Few technologies have caused more concern in the general population than the so called hydraulic fracturing technique, applied to enhance the hydraulic conductivity of resource-bearing rocks by injecting high pressure fluids.

Few technologies have caused more concern in the general population than the so called hydraulic fracturing technique, applied to enhance the hydraulic conductivity of resource-bearing rocks by injecting high pressure fluids. The concern revolves around uncertainty with leakage of used chemicals to overlying aquifers, unwanted seismic events and surface subsidence. This research, combining experimental and computational investigations, aims to establish fundamental understanding of key processes controlling fracture formation in brittle materials (coal seams and porous rocks) under the action of hydraulic fracturing. The research outcomes will help to assess and minimise the risks associated with the hydraulic fracturing technology. Read moreRead less

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
