Dr. Matthew Covington is awarded an NSF Earth Science Postdoctoral Fellowship to carry out a program of research and education at the University of Missouri - Columbia. Dr. Covington will augment computer models for karstic aquifers that relate the geometry of the conduit to recharge and discharge. These models will be tested against natural systems, Devli's Icebox and Maramec Springs, in Missouri. Monitoring stations for water level and temperature will be placed in the main recharge and discharge areas of these two aquifers; these three parameters will be entered into the computer models to draw conclusions about the geometry of the conduit. The results from this investigation will provide information on the geometry of the conduit network in karstic aquifer systems, a factor of critical importance when managing water resources for significant number of the population. In addition, Dr. Covington will establish an outreach program to local high schools to share with students his experiences and anecdotes while exploring caves for recreational and scientific purposes. Dr. Covington will also teach an introductory level Geology class.

马修·科文顿博士被授予美国国家科学基金会地球科学博士后奖学金，在密苏里大学哥伦比亚分校开展研究和教育项目。卡文顿博士将加强岩溶含水层的计算机模型，这些模型将管道的几何形状与补给和排放联系起来。这些模型将在密苏里州的Devli‘s Icebox和Maramec Springs等自然系统上进行测试。水位和温度监测站将放置在这两个含水层的主要补给区和排泄区；这三个参数将输入计算机模型，以得出关于管道几何形状的结论。这项调查的结果将提供有关岩溶含水层系统中管道网络几何形状的信息，这是为大量人口管理水资源时的一个至关重要的因素。此外，科文顿博士还将建立一个面向当地高中的外展项目，与学生们分享他在探索用于娱乐和科学目的的洞穴时的经验和轶事。科文顿博士还将教授一门地质学入门课程。
