0537383WicksThroughout the nation, karstic aquifers serve as the source of drinking water for millions of people. In order to protect and manage this resource, hydrogeologists have to understand the fundamental fluid flow and associated heat and mass transfer processes within karstic aquifers. Currently, there is a lack of understanding of these fundamental processes. Therefore, the goal of the project is to build a community of scientists who will test the foundations of karst hydrology through collective thinking and thoughtful use of first-stage numerical models. These first-stage models are the C-Q models (phase-plane plots), a single-reservoir linear-systems model, and a pipe-flow model that incorporates calcite dissolution. By thoughtful use of these first-stage models, the community will be able to establish the processes govern fluid flow and associated mass and heat transfer in karstic aquifers. This framework will be used in subsequent proposal development. The approach will be to use a graduate-level karst hydrology course as a community of scientists. Management to sustain the availability of water in suitable amounts and quality in karst aquifers requires better models to predict flow and transport. This project will continue development of this goal, while providing training opportunities for future science teachers. The community of graduate students will work together to resolve the fundamental fluid flow problems in karstic aquifers. The involvement of graduate students in field work, modeling, and analysis in karst hydrology will provide important training. These educational activities will teach graduate students through the exercise of model implementation and that the experience of trying and testing modeling options would lay important groundwork for future research by the entire karst community.

0537383Wicks 在全国范围内，岩溶含水层是数百万人的饮用水源。 为了保护和管理这一资源，水文地质学家必须了解岩溶含水层内的基本流体流动以及相关的热量和质量传递过程。 目前，人们对这些基本过程缺乏了解。 因此，该项目的目标是建立一个科学家社区，通过集体思考和深思熟虑地使用第一阶段数值模型来测试喀斯特水文学的基础。 这些第一阶段模型是 C-Q 模型（相平面图）、单储层线性系统模型和包含方解石溶解的管流模型。 通过深思熟虑地使用这些第一阶段模型，社区将能够建立控制岩溶含水层中流体流动以及相关质量和热量传递的过程。 该框架将用于后续提案开发。 该方法将利用研究生水平的喀斯特水文学课程作为科学家群体。管理以维持岩溶含水层中适当数量和质量的水的可用性需要更好的模型来预测流量和运输。 该项目将继续发展这一目标，同时为未来的科学教师提供培训机会。 研究生社区将共同努力解决岩溶含水层中的基本流体流动问题。 研究生参与岩溶水文学的实地工作、建模和分析将提供重要的培训。 这些教育活动将通过模型实施的练习来教导研究生，尝试和测试建模选项的经验将为整个喀斯特社区的未来研究奠定重要的基础。
