The goal of this NSERC Discovery Grant is examining important fundamental and applied problems concerning large-scale groundwater systems that have emerged in the geoscience and engineering communities such as the sustainability of groundwater use and unresolved connections between groundwater and other Earth systems such as the climate and oceans. My long-term research objective is to examine fundamental hydrogeological processes at multiple scales as well as the interactions between groundwater, Earth processes and society to enable sustainable groundwater use. The objective of this grant is to test five exciting hypotheses:1) groundwater interactions with other Earth systems such as the climate and oceans cluster spatially and critical transitions in groundwater-surface water systems can be predicted;2) global groundwater model performance is within the uncertainty of observations and models can estimate the planetary boundary for groundwater use;3) global permeability mapping can be improved with data from fault zones and greater depths;4) the risk of groundwater contamination can be evaluated globally; and5) renewable energy is a potential economic alternative for unsustainable groundwater use.The hypotheses are exciting since they will help resolve the connections between groundwater and other Earth systems as well as make tangible steps towards groundwater sustainability.This research is in the emerging field of mega-scale hydrogeology' that examines groundwater systems at regional (10's km) to continental (1000's km) scales. The field is poised to make significant breakthroughs and impact as groundwater processes are integrated into more regional to global models over the next five years. I propose an ambitious and diverse research program with exceptional HQP training that will hopefully position me to become an international leader within this field.These studies have significant impact on current national and international concerns such as water security, ecosystem services and renewable energy production. This research program directly contributes to national research priorities of sustainable management of groundwater and low-emission energy systems as well as international priorities such as the UN Sustainable Development Goal for protecting water-related ecosystems. These studies will also significantly impact the geosciences by 1) highlighting where groundwater is important to other Earth systems and improving the next generation of Earth system models and 2) evaluating the ecological limits of groundwater use and how these could be maintained through renewable energy generation. Strategically, this research program will enhance Canada's profile in this critical field of mega-scale groundwater systems, especially as water resources emerge as a significant global concern and part of global Earth system models for the first time.

NSERC 发现补助金的目标是研究地球科学和工程界出现的有关大规模地下水系统的重要基础和应用问题，例如地下水利用的可持续性以及地下水与其他地球系统（例如气候和气候）之间未解决的联系。海洋。我的长期研究目标是研究多个尺度的基本水文地质过程以及地下水、地球过程和社会之间的相互作用，以实现地下水的可持续利用。这笔赠款的目的是测试五个令人兴奋的假设：1）地下水与其他地球系统（例如气候和海洋）的相互作用在空间上聚集，并且可以预测地下水-地表水系统的关键转变；2）全球地下水模型的性能在观测和模型的不确定性可以估计地下水利用的地球边界；3）可以利用断层带和更大深度的数据改进全球渗透率绘图；4）可以在全球范围内评估地下水污染的风险； 5) 可再生能源是不可持续地下水利用的潜在经济替代方案。这些假设令人兴奋，因为它们将有助于解决地下水与其他地球系统之间的联系，并为实现地下水可持续性迈出切实步骤。这项研究属于新兴的巨型领域“尺度水文地质学”，以区域（10 公里）到大陆（1000 公里）尺度检查地下水系统。随着地下水过程在未来五年内被纳入更多区域乃至全球模型中，该领域有望取得重大突破和影响。我提出了一项雄心勃勃且多样化的研究计划，并提供卓越的 HQP 培训，有望使我成为该领域的国际领导者。这些研究对当前国家和国际关注的问题（例如水安全、生态系统服务和可再生能源生产）产生重大影响。该研究计划直接促进地下水可持续管理和低排放能源系统的国家研究优先事项以及保护与水有关的生态系统的联合国可持续发展目标等国际优先事项。这些研究还将通过以下方式对地球科学产生重大影响：1）强调地下水对其他地球系统的重要性并改进下一代地球系统模型；2）评估地下水使用的生态限制以及如何通过可再生能源发电来维持这些限制。从战略上讲，该研究计划将提高加拿大在大型地下水系统这一关键领域的形象，特别是在水资源首次成为全球关注的重要问题并首次成为全球地球系统模型的一部分的情况下。
