CAREER: Quantifying drought and vulnerability indicators for water security in a changing environment

PI: Mishra， Ashok这个项目将为极端干旱下改善水资源可持续性创造一个新模式，并将其引入科学、社会和政策团体。模型的结果将分发给目前正在处理水的可持续性问题的用户群体，他们将来可能也会这样做。预计该项目将直接惠及地区利益相关者，使其能够在干旱条件下改善水资源管理，并协助联邦机构提前预测与利益相关者相关的水资源压力脆弱性。综合模式和方法将在萨凡纳河流域进行试验，预计该方法将推广到该国其他地区，这些地区的水安全经常受到干旱威胁。目标是通过解决三个研究目标来评估极端干旱背景下的水安全。具体而言，前两个研究目标将侧重于通过评估依赖结构、级联行为和脆弱性阈值来量化干旱-水安全关系，而第三个目标是将该方法应用于利用季节预测和利益相关者信息来改进决策。研究目标将与一项多学科教育和研究计划紧密联系起来，该计划旨在为目前的水不安全问题提供解决办法。

CBET 1653841 PI: Mishra, Ashok This project will create a new model for improving water sustainability under extreme droughts and introduce it to the scientific, social and policy communities. The model results will be distributed to user groups who are currently coping with water sustainability issues and will likely do so in the future. The project is anticipated to directly benefit regional stake holders to enable improved management of water resources during drought conditions, and also to assist federal agencies to forecast vulnerability to water stress in advance times that are relevant to stakeholders. The integrated model and approach will be tested in the Savannah River Basin, and it is anticipated that the methodology will be extendible to other parts of the country that witness frequent drought threats to water security.The goal is to evaluate water security in the context of drought extremes by addressing three research objectives. Specifically, the first two research objectives will focus on quantifying the drought-water security relationship by evaluating dependence structure, cascade behavior and vulnerability threshold, while the third objective is to apply the approach to improve decision making using seasonal forecast and stakeholder information. The research objectives will be tightly connected with a multidisciplinary education and research plan designed to provide solutions to current water insecurity problems.
