TERRESIM: A simulation system for understanding and managing the interactions between runoff, vegetation, soils and climate in a changing environment. The landforms around us evolve in response to the processes of hydrology, erosion, climate and vegetation that develops on them. Likewise, the past behaviour of these processes (thus historical climatic fluctuations) in written in the deposited sediment. To study these interactions will be develop a state-of-the-art landform simulator (TerreSim). ....TERRESIM: A simulation system for understanding and managing the interactions between runoff, vegetation, soils and climate in a changing environment.

Likewise, the past behaviour of these processes (thus historical climatic fluctuations) in written in the deposited sediment. To study these interactions will be develop a state-of-the-art landform simulator (TerreSim). We will use it to explore the evolution, development and sustainability of soils, vegetation, and hydrology (e.g. water supply) so as to better understand their response to climatic changes. We will also study rates of cliff retreat and debris flow in steep landscapes to better understand cliff stability.Read moreRead less
Sediment stock-piling and the fate of Australian floodplains. Historic landuse practices have profoundly altered Australia's river systems in less than 200 years. Up to 80% of the sediment and associated pollutants eroded from Australia's catchments are stored in floodplains. The assumption that floodplains can continue to absorb the impacts of upland erosion and land degradation is extremely risky, yet it underpins current catchment management policies in Australia. This project delivers essent ....Sediment stock-piling and the fate of Australian floodplains. Historic landuse practices have profoundly altered Australia's river systems in less than 200 years. Up to 80% of the sediment and associated pollutants eroded from Australia's catchments are stored in floodplains. The assumption that floodplains can continue to absorb the impacts of upland erosion and land degradation is extremely risky, yet it underpins current catchment management policies in Australia. This project delivers essential data on floodplain storage and remobilisation rates using innovative sediment dating and tracing technologies. The significance of this research lies in its immediate relevance to rural industries and the management of Australian riverine and offshore ecosystems.

Soil erosion and river system response to climate change and early human activity in Australia. This project will provide a much needed quantitative understanding of how soils and rivers have responded and adapted to climate change and human activity in Australia. The outcomes will inform models to predict how our environment is likely to adapt to new conditions in the future as a result of indirect (global warming) and direct (intensive land use) human-related stresses. This project will contri ....Soil erosion and river system response to climate change and early human activity in Australia.

This project will contribute to the innovative character of Australian research through the development and implementation of new approaches to study soil and river processes.Read moreRead less

This project will assess the extent and rate of depletion of soil resources in Australia and also contribute to the innovative character of Australian research through the development and implementation of a new approach to study soil and river processes.Read moreRead less
Developing a decision support system for the management of road runoff for water quality protection. Multiple stakeholders share a vested and often significant financial commitment to ensure water quality standards. These industries, in turn, are vital to the social and economic sustainability of many rural communities in Australia. Recent climatic trends of increasing drought episodes and related natural disasters such as bushfires are expected to increase the delivery of sediments and associat ....Developing a decision support system for the management of road runoff for water quality protection. Multiple stakeholders share a vested and often significant financial commitment to ensure water quality standards. These industries, in turn, are vital to the social and economic sustainability of many rural communities in Australia. Recent climatic trends of increasing drought episodes and related natural disasters such as bushfires are expected to increase the delivery of sediments and associated pollutants to streams. The proposed DSS will allow testing of various management scenarios with respect to road position and layout, thereby providing a planning and management tool, and a method to educate the practitioners involved in environmental management in Australia.

Anabranching rivers: the arteries of arid Australia. Multi-channel (anabranching) rivers are prevalent among the world's largest rivers and span vast areas of arid Australia, yet no comprehensive explanation exists for how or why they occur. This study determines why rivers anabranch, why Australia has them in such abundance, and how best to manage them for agricultural production and conservation.
A next generation spatially distributed model for soil profile dynamics and paedogenesis incorporating soil geochemistry and organic matter. Soil is the interface between the land, atmosphere, and biosphere. We are unable to fully characterise it because it varies in space and data collection is difficult. This project will develop models of soil formation to understand the spatial distribution of soil and how this distribution links with its biogeochemical role in the environment.
The big flood: will it happen again? If we could better predict the frequency of extreme flood events, would we be better prepared to safeguard human lives and settlements? This project provides a time-line of flood activity in the south east Queensland region extending back thousands of years using state-of-the-art dating techniques and seeks to identifiy those settlements most at risk.
Will rivers be smaller when the climate is hotter? This project aims to investigate how large rivers are affected by changing atmospheric temperature. Large inland rivers are the main source of water supporting ecological functions, economies and societies. This project will quantify the size and age of abandoned river channels in the Murray-Darling Basin (MDB) of southeast Australia and the Atuel/Diamante basin of Argentina. We will use this to reconstruct a history of changes in river discharg ....Will rivers be smaller when the climate is hotter? This project aims to investigate how large rivers are affected by changing atmospheric temperature. Large inland rivers are the main source of water supporting ecological functions, economies and societies. This project will quantify the size and age of abandoned river channels in the Murray-Darling Basin (MDB) of southeast Australia and the Atuel/Diamante basin of Argentina. We will use this to reconstruct a history of changes in river discharge and relate this to climate. Novel climate and hydrological modelling will then be used to simulate the impact of temperature changes on catchment runoff and river discharge. Such information is vital for decision-making, planning and water resource allocation in the MDB and elsewhere. Read moreRead less

This equipment will support projects that address significant environmental challenges in Australia, such as climate change and variability, coastal management and sustainable river and water management, and that assess the impacts and consequences of these challenges for populations living in environmentally sensitive areas. These projects will build on established collaborations in Australia, Antarctica and the south-west Pacific and encourage new collaborations with south-east Asian, Egyptian and Argentinean researchers, which will promote Australian research on a world stage. The use of this equipment will also pioneer new dating methodologies to further enhance Australia's place at the forefront of geochronology.Read moreRead less
