Assessment of the Mass Flux in a Benthic Boundary Layer of a Stratified Lake. 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, ....Assessment of the Mass Flux in a Benthic Boundary Layer of a Stratified Lake. 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
Ecological renovation of constructed wetlands: changing state from algae to macrophyte dominated systems. Mars Confectionary's constructed wastewater treatment wetlands no longer purify its waste waters. Over-burdening has tipped the balance from a plant dominated, clear water system to an algae dominated, turbid system. This project will aid restoration of the Mars wetlands by (1) improving our understanding of alage-macrophyte dynamics in shallow water basins; (2) producing a series of soft en ....Ecological renovation of constructed wetlands: changing state from algae to macrophyte dominated systems. Mars Confectionary's constructed wastewater treatment wetlands no longer purify its waste waters. Over-burdening has tipped the balance from a plant dominated, clear water system to an algae dominated, turbid system. This project will aid restoration of the Mars wetlands by (1) improving our understanding of alage-macrophyte dynamics in shallow water basins; (2) producing a series of soft engineering, ecologically based techniques for the management / rehabilitation of natural and constructed shallow water bodies which receive high nutrient loads; (3) improve decision support tools for the renovation and sustainable management of the Mars Confectionary, and similar food processing industry constructed wetlands.Read moreRead less
Predicting plankton patchiness in lakes using a high resolution sampling system. This research will benefit Australian Society through a better understanding and prediction of the response of aquatic systems to major shifts in the environment. Eutrophication and toxic algal blooms represent serious threats to the security of water supplies in Australia and elsewhere. Through development of high resolution technology (SPS), this project will provide the necessary knowledge and data for producing ....Predicting plankton patchiness in lakes using a high resolution sampling system. This research will benefit Australian Society through a better understanding and prediction of the response of aquatic systems to major shifts in the environment. Eutrophication and toxic algal blooms represent serious threats to the security of water supplies in Australia and elsewhere. Through development of high resolution technology (SPS), this project will provide the necessary knowledge and data for producing management tools capable of detailed predictions of the behaviour of aquatic systems. Successful management of Australian waters relies heavily on a better understanding of the scale dependent processes which govern the response to external perturbations such as increased nutrient export and consequent eutrophication.Read moreRead less

Maximizing reservoir water quality security through the use of a Lake Diagnostic System (LDS) and a Controlled Lagrangian Drogue (CLD). It is proposed to build on recent advancements in limnological research and existing measurement technologies to develop the hardware, algorithms and software to form a unique real time reservoir water quality management system, driven by minimal measurement inputs. This will remove the reliance on extensive expensive reservoir monitoring, previously necessary ....Maximizing reservoir water quality security through the use of a Lake Diagnostic System (LDS) and a Controlled Lagrangian Drogue (CLD). It is proposed to build on recent advancements in limnological research and existing measurement technologies to develop the hardware, algorithms and software to form a unique real time reservoir water quality management system, driven by minimal measurement inputs. This will remove the reliance on extensive expensive reservoir monitoring, previously necessary to characterize the lake spatial variability and seasonality, for full 3D modelling. This project will deliver to industry: two measurement tools to simplify reservoir monitoring, the LDS and CLD; and software tools to manage real time data collection, provide decision support to reservoir managers and to enable ?on-demand? scenario predictions.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 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
