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.
Hydrologic effects of human and climatic stresses in water-limited areas: role of coevolving runoff, vegetation and landforms for adaptive management. Semiarid rangelands cover over 70 per cent of the Australian continent. These areas already face serious degradation problems. Observed trends in rainfall variability indicate that high rainfall pulses and dry periods will intensify, with serious implications for hydrology and erosion. The impact of these trends in addition to increasing human pre ....Hydrologic effects of human and climatic stresses in water-limited areas: role of coevolving runoff, vegetation and landforms for adaptive management. Semiarid rangelands cover over 70 per cent of the Australian continent. These areas already face serious degradation problems. Observed trends in rainfall variability indicate that high rainfall pulses and dry periods will intensify, with serious implications for hydrology and erosion. The impact of these trends in addition to increasing human pressures could have devastating socioeconomic consequences for these areas. This project, by examining in detail the hydrologic and soil transport processes in semiarid rangelands, will lead to: better understanding of the dryland response to anthropogenic and climatic stresses; and, improvement of strategies and methods for the management and restoration of these areas.Read moreRead less
Catchment water balance and CO2 fluxes: a comparison between productive land uses. The aim of the project is to improve the understanding of different land use implications on water resource and land productivity. The project aims to use a paired-catchment study that compares the carbon and water balances in two catchments in the high rainfall zone in south western Victoria. One catchment is used prevalently for grazing, while the other is predominantly planted with blue gums. The main objective ....Catchment water balance and CO2 fluxes: a comparison between productive land uses. The aim of the project is to improve the understanding of different land use implications on water resource and land productivity. The project aims to use a paired-catchment study that compares the carbon and water balances in two catchments in the high rainfall zone in south western Victoria. One catchment is used prevalently for grazing, while the other is predominantly planted with blue gums. The main objectives of this project are: to quantify the effect of different agricultural land uses on the catchment water balance; to estimate the trade-off between carbon sequestration and water resources related to tree plantations and pastures; and to develop models at different spatial scales of catchment water balance for land-use management.Read moreRead less
Preserving vegetation health and biodiversity of natural, urban reserves. The aim of this project is to quantify the links between water resources, vegetation health and biodiversity in small native and remnant vegetation reserves embedded in urban environments. The project will examine four reserves within Greater Melbourne hosting native tree species (river red gum), identified as vulnerable or endangered, and experiencing different rainfall regimes as well as water management practices. The s ....Preserving vegetation health and biodiversity of natural, urban reserves. The aim of this project is to quantify the links between water resources, vegetation health and biodiversity in small native and remnant vegetation reserves embedded in urban environments. The project will examine four reserves within Greater Melbourne hosting native tree species (river red gum), identified as vulnerable or endangered, and experiencing different rainfall regimes as well as water management practices. The specific objectives are to quantify water requirements and carbon balances, and to test a set of measurement methods (in situ and remote sensing) to relate water use with tree growth and biodiversity in urban reserves. Based on these studies, the project aims to develop a model for water balance and vegetation growth to assist in the management of urban reserves and parks.Read moreRead less
Optimising permeable pavements with underlying reservoirs to enhance urban tree performance. This project will determine the optimal configuration of permeable pavements with underlying storage reservoirs and water delivery system to resolve the water security challenges that trees face in urban environments. This project will promote the healthy growth of urban trees and will lead to more liveable and healthier cities.
