Understanding the underlying processes responsible for Benthic Bundary Layer (BBL) mass flux in stratified lakes is of fundamental ecological importance. By verifying the ability of the current Centre for Water Research hydrodynamics models to reproduce the dynamics of the BBL, Australia will cement its position as an international leader in the development of technologies to guide the management of lakes, reservoirs, estuaries and coastal areas. Furthermore, these water bodies are important sources and sinks of carbon and the extent to which they contribute to the national and international carbon inventory can be assessed using this technology.Read moreRead less
Factors controlling phytoplankton patchiness in a seasonally stratified lake. This project will determine what processes result in the formation of phytoplankton patches in lakes, over what scale, and how they can be parameterized into models to assist in managing aquatic systems. This will allow key parameters to be measured at the correct time and space scales. The Controlled Lagrangian Drogue coupled with correctly parameterized hydrodynamic and water quality models will provide the Austra ....Factors controlling phytoplankton patchiness in a seasonally stratified lake. This project will determine what processes result in the formation of phytoplankton patches in lakes, over what scale, and how they can be parameterized into models to assist in managing aquatic systems. This will allow key parameters to be measured at the correct time and space scales. The Controlled Lagrangian Drogue coupled with correctly parameterized hydrodynamic and water quality models will provide the Australian and International water industry with tools to measure and predict phytoplankton patchiness and make decisions about water quality treatment, offtake regimes and reservoir management. This will minimize the economic costs of water quality management and enhance the security of the quality of our water resources. Read moreRead less
Resilience of lake ecosystems to water-level manipulation. Which lakes recover from fluctuations in water level and which do not? Manipulations of water levels in lakes will need to intensify as droughts become more frequent. This project will develop robust ways of forecasting how lakes will respond to changes in manipulations of water levels, to minimise extinctions and maintain aesthetics and water quality.
