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.

该项目将确定哪些过程导致湖泊浮游植物斑块的形成，以何种规模形成，以及如何将它们参数化到模型中，以协助管理水生系统。这将允许在正确的时间和空间尺度上测量关键参数。控制拉格朗日德鲁格与正确参数化的水动力和水质模型相结合，将为澳大利亚和国际水工业提供测量和预测浮游植物斑块的工具，并为水质处理、摄取量制度和水库管理做出决策。这将尽量减少水质管理的经济成本，并加强我们水资源的质量安全。
