U.S.-Brazil Collaboration: Investigation of Subsurface Contaminant Mass Flows

这项美巴合作项目包括来自佛罗里达大学土木工程系的美国科学家Kirk Hatfield、Michael Annable和Clayton Clark。巴西的同行包括科学家Joana Luz、Olivar Lima和Eduardo Savio。拟议的合作将带来解决地下水污染的知识交流，这是巴西萨尔瓦多日益严重的问题。这个合作研究项目的重点是开发一种量化地下污染物质量流和相关估计不确定性的新方法。研究将通过基于年度相互计划访问的合作努力在巴西进行，美国小组将协助扩大已经在巴伊亚联邦大学进行的与通量计有关的初步实验。两名美国学生每年将在巴西进行一个学期的实验室和实地工作，两名美国教师也将每年前往巴西两周。美国团队将与巴伊亚联邦大学（UFBA）的巴西同事一起测试新的实验室方法。双方参与调查人员的专业知识是互补的，其中包括巴西小组对热带污染物和水文地质条件的熟悉以及地球物理方面的专业知识，以及美国小组对通量计方法和发展的详细知识。该奖项由工程理事会的土木、机械和制造创新司和国际科学与工程办公室（OISE）联合支持。

Hatfield0804134This US-Brazil collaboration includes US scientists Kirk Hatfield, Michael Annable and Clayton Clark form the University of Florida, Department of Civil Engineering. Brazilian counterparts include scientists Joana Luz, Olivar Lima and Eduardo Savio. The proposed collaboration will bring an exchange of knowledge to solve groundwater contamination which is a growing problem in Salvador, Brazil.This collaborative research project focuses on developing a new methodology for quantifying subsurface contaminant mass flows and associated estimation uncertainties. Research will be conducted in Brazil through a collaborative effort based on annual mutual planning visits, where the US team will assist in the expansion of preliminary flux meter related experiments already conducted at the Bahia Federal University. Two US students will be involved in laboratory and field work in Brazil for a semester each year and two US faculty members will also travel to Brazil for two weeks each year. The US team will test new laboratory methods with Brazilian colleagues at the Universidade Federal da Bahia (UFBA). There is complementary expertise of the participating investigators on both sides, which include the familiarity with tropical contaminant and hydrogeological conditions as well as the geophysical expertise of the Brazilian team and the detailed knolwedge about the fluxmeter methodology and development of the US team. This award is being jointly supported by the Division of Civil, Mechanical and Manufacturing Innovation in the Engineering Directorate and the Office of International Science and Engineering (OISE).
