Diagnosing river health using invertebrate traits and DNA barcodes. This project aims to develop indices that link change in invertebrate communities to specific environmental stressors, and combine these indices with innovative, low cost molecular approaches to species identification to rapidly identify the causes of decline. River health assessment methods, usually based on aquatic invertebrates, identify if rivers are impaired but must be developed to identify the causes of decline. The intended outcomes are improved sustainable water resource management within and among states, and improved natural resource policy development.Read moreRead less
Conservation tillage and its potential to affect catchment salt and water balances. Replacement of deep-rooted vegetation with shallow rooted crops has resulted in greater movement of water into groundwater systems, raising in groundwater level and mobilizing salt to the land's surface. The practice of conservation tillage, provides a range of advantages to landholders, but also has the potential to accentuate the risk of salinisation because it increases water infiltration into the soil surfac ....Conservation tillage and its potential to affect catchment salt and water balances. Replacement of deep-rooted vegetation with shallow rooted crops has resulted in greater movement of water into groundwater systems, raising in groundwater level and mobilizing salt to the land's surface. The practice of conservation tillage, provides a range of advantages to landholders, but also has the potential to accentuate the risk of salinisation because it increases water infiltration into the soil surface. This project aims to evaluate the impact of conservation tillage on soil salt profiles in the Condamine-Balonne and Border Rivers Catchments, and to model will the effect of changed landscape salt and water balances on river water quality.Read moreRead less

The project intends to use a new, high-resolution, open-access, multi-regional, input-output model of the Australian economy and its resources u ....Mapping the water-energy nexus: new knowledge for resources security. This project plans to systematically evaluate energy impacts of urban water security across three interconnected systems: the direct consequences of water supply; the indirect influence of water use in industry and homes; and the remote implications of water security on supply chains. The project intends to use a new, high-resolution, open-access, multi-regional, input-output model of the Australian economy and its resources use: the Industrial Ecology Virtual Laboratory. It expects to help address escalating energy demands and costs for urban water by identifying alternative and optimal pathways for addressing the energy impacts of water supply.Read moreRead less

Endocrine disrupting chemicals (EDCs) can produce alarming detrimental impacts on the reproduction and survival of aquatic species, though little is presently known in terms of their effect and impacts on sensitive marine invertebrate species. We propose the development and validation of the first marine mollusc as a biomonitor for the detection and impact assessment of estrogenic contaminants in Australian estuarine and marine waterbodies. Such biomonitors will provide water management agencies with the capability to manage estrogenic effluent discharges and provide the oyster industry with a tool to prevent product contamination, ensuring the continued health and sustainability of our aquatic resources.Read moreRead less
The effect of chlorine disinfection byproducts in wastewater effluent on the aquatic environment. Chlorination of treated wastewater leads to the formation of harmful disinfection byproducts (DBPs). A key issue for the water industry and government environmental agencies is whether the DBPs have a deleterious effect on organisms in the receiving aquatic environment. The effect of fractions of chlorinated and chlorinated/dechlorinated wastewaters on organisms will be assessed using biological as ....The effect of chlorine disinfection byproducts in wastewater effluent on the aquatic environment. Chlorination of treated wastewater leads to the formation of harmful disinfection byproducts (DBPs). A key issue for the water industry and government environmental agencies is whether the DBPs have a deleterious effect on organisms in the receiving aquatic environment. The effect of fractions of chlorinated and chlorinated/dechlorinated wastewaters on organisms will be assessed using biological assays. Chemical analysis will be used to identify the compounds in fractions having negative biological effects. Laboratory data will be validated by measuring environmental DBP concentrations and assessing the biota. This project will identify the risk to biota in aquatic environments from chlorinated and chlorinated/dechlorinated wastewater.Read moreRead less
