淡水的供应和质量不仅影响到人类的健康和福祉，而且影响到河流、湿地、湖泊和河口等基本生态系统的运作。水的巨大效用也证明了它的毁灭性，因为淡水资源的可持续性在世界范围内受到过度使用和其他压力的威胁。因此，迫切需要制定新的办法来管理我们有限的水资源。 大多数可用的淡水以地下水的形式存在。地下水和地表水之间的交换发生在整个景观中，它们支持大量的关键生态系统服务。拟议的CERC研究计划是一个多学科的努力，致力于建立一个更好的和定量的了解地下水管理替代方案和水生生态系统健康的后果之间的关系。 该计划将特别关注将地下水与地表沃茨分隔开的界面上营养物和重金属的通量。本研究将联合收割机实验室和现场试验以及数学建模相结合。 这些实验和实地测量将评估地下水-地表水混合区普遍存在的动态环境条件下生物地球化学转化的速率、机制和产物。

The availability and quality of freshwater not only impact human health and well-being, but also the functioning of essential ecosystems, including rivers, wetlands, lakes and estuaries. The great utility of water has also proven its undoing, as the sustainability of freshwater resources is threatened worldwide by over-usage and other stresses. There is thus an urgent need to establish new ways to manage our limited water resources. Most available freshwater is present as groundwater. Exchanges between groundwater and surface water occur throughout the landscape and they support a plethora of key ecosystem services. The proposed CERC research program is a multidisciplinary effort dedicated to establishing an improved and quantitative understanding of the relationships between groundwater management alternatives and the consequences for aquatic ecosystems health. The program will have a particular focus on the fluxes of nutrients and heavy metals across interfaces separating groundwater from surface waters. The research will combine laboratory and field experiments and mathematical modeling. The experiments and field measurements will assess the rates, mechanisms and products of biogeochemical transformations under the dynamic environmental conditions that commonly prevail in groundwater–surface water mixing zones.
