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

这个美国和巴西的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柯克·哈特菲尔德、迈克尔·安纳博和克莱顿·克拉克。巴西同行包括科学家Joana Luz、Olivar Lima和Eduardo Savio。拟议的合作将带来知识交流，以解决巴西萨尔瓦多日益严重的地下水污染问题。这一合作研究项目的重点是开发一种新的方法来量化地下污染物质量流量和相关的估计不确定性。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，美国团队将协助扩大已经在巴伊亚联邦大学进行的与流量计相关的初步实验。两名美国学生每年将在巴西进行为期一学期的实验室和实地工作，两名美国教职员工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。双方参与的调查人员有互补的专业知识，包括熟悉热带污染物和水文地质条件，以及巴西团队的地球物理专业知识，以及关于流量计方法和美国团队发展的详细知识。该奖项由工程局土木工程、机械和制造业创新司和国际科学与工程办公室(OISE)共同支持。

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).
