Improving water quality, primarily through reducing nutrient concentrations, remains a massive challenge for effective catchment management in Australia. Through a multidisciplinary approach including soil science, hydrology and aquatic chemistry, this project will develop an integrated catchment system understanding of water quality behaviour. This understanding will greatly improve the scientific underpinning of catchment water quality management and prediction, thus supporting improvements in the sustainability of Australia's water management. The work will focus on catchments with high intensity livestock grazing, which tend to be located in high rainfall areas near coasts where significant issues of water quality management exist.

改善水质，主要是通过降低营养物浓度，仍然是澳大利亚有效集水管理的一个巨大挑战。 通过包括土壤科学、水文学和水化学在内的多学科方法，该项目将发展对水质行为的综合集水系统理解。 这一认识将大大改善集水区水质管理和预测的科学基础，从而支持澳大利亚水管理的可持续性的改善。 这项工作将侧重于牲畜放牧强度高的集水区，这些集水区往往位于靠近海岸的高降雨区，那里存在着严重的水质管理问题。
