Develop a model to accurately predict the full details of flow in saline river ponds subjected to a freshwater overflow. Such ponds are ubiquitous in Australia's inland rivers, have low oxygen and high nutrient and salinity levels and are associated with poor water quality, both in the pond and downstream during flow events. The model will allow precise determination of the river flow rates required to fully purge ponds and the downstream effect of the low quality pond water on the riverine environment and will also assist in the devlopment of rule of thumb scaling formula that will be incorporated into a one-dimensional flow prediction model being developed by the industrial partner.

开发一个模型，以准确地预测淡水溢流情况下咸水河池塘中流动的全部细节。这类池塘在澳大利亚的内河中随处可见，氧气含量低，营养盐水平高，在水流事件期间，池塘和下游的水质都很差。该模型将能够精确地确定完全冲刷池塘所需的河流流量以及低质量池塘水对河流环境的下游影响，并将有助于开发经验法则比例公式，该公式将被纳入工业合作伙伴正在开发的一维流量预测模型中。
