9978192SillimanThis is a planning visit award for Dr. Stephen E. Silliman, of the Department of Civil Engineering and Geological Sciences at the University of Notre Dame, to travel to Benin to meet with Dr. Moussa Boukari, of the Department of Earth Sciences at the Universite Nationale du Benin. The purposes of the visit are to develop a cooperative research project for the delineation of groundwater flow through fractured rock masses, and collect initial geochemical and historical data sets from ten sites. In Benin, as elsewhere in Africa, high-quality water in ample quantities for domestic use is very scarce. Much of Benin's water supply is provided by wells which are hand dug or drilled into fractured crystalline rock, but the lack of ability to identify where the best sources of water are located produces many dry wells. The proposed research activity will study the complex interrelationships among fracture location, geology, geochemistry, remote imaging, and indigenous knowledge about local water systems and drilling histories. The results are expected to produce a scientific method for locating high-quality water sources in fractured crystalline rock formations. Funding for this project is being provided jointly by the Division of International Programs and the Division of Earth Sciences.

9978192Silliman这是圣母大学土木工程和地质科学系的Stephen E.Silliman博士前往贝宁与贝宁国立大学地球科学系的Moussa Boukari博士会面的计划访问奖。这次访问的目的是开发一个合作研究项目，以描绘通过裂隙岩体的地下水流动，并从10个地点收集初步的地球化学和历史数据集。在贝宁，与非洲其他地方一样，供家庭使用的高质量充足的水非常稀缺。贝宁的大部分供水是由手工挖掘或钻入破碎的结晶岩中的水井提供的，但由于缺乏识别最佳水源所在位置的能力，因此产生了许多枯井。拟议的研究活动将研究裂缝位置、地质学、地球化学、遥感成像和关于当地水系和钻探历史的土著知识之间的复杂相互关系。这一结果有望为寻找裂隙结晶岩层中的优质水源提供一种科学方法。该项目的资金由国际方案司和地球科学司联合提供。
