U.S.-Spain Cooperative Research: Using Semi-Analytical Methods to Solve Scale-Dependent Contaminant Transport Equations in Heterogeneous Aquifers

93221592 Serrano这个为期两年的奖项支持肯塔基大学的Sergio Serrano和西班牙巴伦西亚理工大学的Andres Sahuquillo之间的美国-西班牙合作研究。他们将合作使用半解析方法来解决非均质含水层中依赖尺度的污染物运移方程。由于在自然条件下遇到许多不同的边界和界面，使得污染物在非均质含水层中运移的微分方程式的求解变得困难。在精细的时空网格上执行数值解方法会使计算速度变慢，从而使该方法无法实现。使用半分析方法提供了一种获得稳定解决方案的替代办法，这可能会导致更准确的预测模型和更好地了解污染物在含水层中的迁移情况。该项目将利用欧洲水文学家更常见的这种方法，以及萨胡基洛博士的专业知识和他在地下水水文学中开发的半分析方法。这一建议有助于欧洲和美洲社区不同方法之间更大的智力互动，这可能导致对这一重要问题的重大贡献。***

93221592 Serrano This two-year award supports U.S.-Spain cooperative research between Sergio Serrano, University of Kentucky, and Andres Sahuquillo, Polytechnic University of Valencia, Spain. They will collaborate on the use of semi-analytical methods to solve scale-dependent contaminant transport equations in heterogeneous aquifers. The solution of the differential equations for contaminant transport in heterogeneous aquifers is made difficult by the many varied boundaries and interfaces encountered under natural conditions. Executing numerical solutions methods on a fine time-space grid slows the computations to an extent that can make the method prohibitive. The use of semi-analytical methods offers an alternative to arrive at stable solutions that may result in more accurate forecasting models and a better understanding of contaminant migration in aquifers. The project will take advantage of this approach, more common to European hydrologists, and the expertise of Dr. Sahuquillo and his development of semi-analytical methods in groundwater hydrology. This proposal contributes to greater intellectual interaction between the different approaches of the European and American communities that may lead to significant contributions to this important problem. * * *
