地下水在五大湖盆地的生命力中发挥着重要作用，为各部分供水。由于该地区地下水和地表水特征的相互联系，地下水质量可能受到影响，导致该地区潜在的经济，政治，健康和社会问题。地下水资源得到的重视较少，这可能是由于“眼不见心不烦”的心态。地下水，特别是城市中心的浅层近地表沃茨的不完整特性是五大湖流域环境脆弱性的另一个来源。本文提供了一个更好的了解城市地下水，以减少这种脆弱性。为此，在这个项目中采用了两种方法来改善密歇根州东南部地下水的特性。在第一种方法中，我们构建了一个区域地下水模型，包括四个主要的流域，以定义大规模的地下水功能。在第二种方法中，我们采用了当地的规模，并制定了当地的城市水预算与随后的地下水模拟。结果表明，地下水运动在两个不同的尺度，暗示城市设置对地下水资源的影响。区域和局部尺度模型都可用于评估和减轻城市中心的环境风险。
Groundwater plays a significant role in the vitality of the Great Lakes Basin, supplying water for various sections. Due to the interconnection of groundwater and surface water features in this region, the groundwater quality can be affected, leading to potential economic, political, health, and social issues for the region. Groundwater resources have received less emphasis, perhaps due to an “out of sight, out of mind” mentality. The incomplete characterization of groundwater, especially shallow, near-surface waters in urban centers, is an added source of environmental vulnerability for the Great Lakes Basin. This paper provides an improved understanding of urban groundwater to reduce this vulnerability. Towards that end, two approaches for improved characterization of groundwater in southeast Michigan are employed in this project. In the first approach, we construct a regional groundwater model that encompasses four major watersheds to define the large-scale groundwater features. In the second approach, we adopt a local scale and develop a local urban water budget with subsequent groundwater simulation. The results show the groundwater movement in the two different scales, implying the effect of urban settings on the subsurface resources. Both the regional and local scale models can be used to evaluate and mitigate environmental risks in urban centers.
