This project aims to assess the vulnerability of freshwater ecosystems to extended droughts in a variable and changing climate. Governments around the world are investing in the restoration of regulated river systems with environmental water. However, the risks of climate change for environmental water management are seldom considered. This project will model the change in environmental and consumptive water use during extended dry periods, and couple this to models of ecological dynamics and failure thresholds. This will improve the success of Australia’s major environmental water programs in sustaining benefits through future multi-year droughts.

该项目旨在评估淡水生态系统在多变和不断变化的气候中对长期干旱的脆弱性。世界各地的政府正在投资恢复受管制的河流系统和环境用水。然而，气候变化对环境水管理的风险却很少得到考虑。该项目将模拟长期干旱期间环境和消耗性用水的变化，并将其与生态动力学和故障阈值模型相结合。这将提高澳大利亚主要环境水方案在未来多年干旱中维持效益的成功率。
