ERCZ: Optimal Management Strategies for Coastal Aquifers under Climate-Induced Changes

该项目将解决诸如抽水、潜在的气候变化和海平面变化等人为力量对沿海含水层的影响。这项工作包括五项分析任务：气候变化导致的海平面上升情景；气候变化引起的径流和地下水补给情景，从全球环流模型(GCM)得出并重新缩放到区域层面；咸水入侵与地下水运移的地下水运移模型；地下水管理优化模型；以及位于加利福尼亚州文图拉县的圣克拉拉/卡列瓜斯地下水盆地的案例研究。这项研究的结果将为气候诱导下沿海含水层的优化管理和运行提供更好的理解。来自海平面上升和地下水补给模式变化的压力。

The project will address the effects of anthropogenic forces, such as pumping, potential climatic changes and sea level changes on coastal aquifers. The work comprises five analytical tasks: climate change-induced scenarios of sea level rise; climate change- induced scenarios of streamflow and groundwater recharge as derived from global circulation models (GCMs) and re-scaled to a regional level; groundwater transport models of salt water intrusion and groundwater movement; a groundwater management optimization model; and a case study on the Santa Clara/Calleguas groundwater basin located in Ventura County, California. Results from this research will provide a better understanding for the optimal management and operation of coastal aquifers under climate-induced stress from both sea level rise and changing groundwater recharge patterns.
