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

哈特菲尔德0804134这项美国和巴西的合作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·安纳布尔和克莱顿·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的交流，以解决地下水污染，这是一个日益严重的问题，在萨尔瓦多，Brazil.This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的质量流量和相关的估计不确定性。研究将在巴西通过基于年度相互规划访问的协作努力进行，美国小组将协助扩大已在巴伊亚联邦大学进行的初步通量计相关实验。两名美国学生将每年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。 美国研究小组将与巴西联邦大学巴伊亚（UFBA）的同事一起测试新的实验室方法。 双方参与的调查人员具有互补的专门知识，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专门知识，以及美国小组对通量计方法和开发的详细知识。 该奖项由工程理事会的土木，机械和制造创新部门以及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).
