Optimising seasonal decisions for environmental water use. This project will develop a tool to optimise the use of environmental water, drawing on seasonal forecasts of streamflow and water price, and predicted ecological responses to changing flows. This tool will strengthen the effectiveness of the government organisations responsible for managing Australia's environmental water reserves.
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
Optimal trade-offs for managing environmental water in inland wetlands. This project aims to optimise long-term water trade-offs in inland wetlands on managed catchments, without compromising their environmental value. These managed wetlands compete for water allocations with irrigation and other uses. Realistic predictions of wetland status will be achieved through the development and integration of an ecohydrological model and a water management decisions model. Application of the tools will i ....Optimal trade-offs for managing environmental water in inland wetlands. This project aims to optimise long-term water trade-offs in inland wetlands on managed catchments, without compromising their environmental value. These managed wetlands compete for water allocations with irrigation and other uses. Realistic predictions of wetland status will be achieved through the development and integration of an ecohydrological model and a water management decisions model. Application of the tools will improve existing decision support models to help analyse the effects of individual local management decisions on the long-term evolution of the system and the effects of changes in operation policies and climate over the long term. The project will provide critical new information for the improved prediction of wetlands evolution and as a consequence better management.Read moreRead less
Robust streamflow predictions by improving the identification of hydrological model structure. This project aims to provide Australian environmental agencies, design engineers and policy-makers with robust methods that better utilise observed environmental data and process understanding to produce hydrological models with stronger scientific basis and improved operational predictive ability in gauged and ungauged catchments.
