0000425FlowersThe International Research Fellow Awards Program enables U.S. scientists and engineers to conduct three to twenty-four months of research abroad. The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will provide Dr. Gwenn E. Flowers with support for 12 months to work with Dr. Helgi Bjornsson, Head of Glaciology at the Science Institute of the University of Iceland in Reykjavik, Iceland.The objective of this project is to understand the dynamics of ice cap hydrology that influence stable and unstable modes of water flow beneath Vatnajkull, Iceland's largest ice cap, and to test, improve and refine a numerical model in preparation for larger-scale investigations. Dr. Flowers will use a numerical model of glacier hydrology that she developed as the core of her doctoral research. She will use information available through the Science Institute of the University on Vatnajkull surface and bed geometry and hydraulic characteristics to evaluate how well the modeled drainage structure honors that which is presently observed. This project represents a first attempt to describe a complete computational picture of glacier hydrology. The results will benefit the field of glacier hydraulics and its impact on glacier dynamics.Dr. Bjornsson has been described as one of Iceland's preeminent glaciologists. He is the current vice-president of the International Glaciological Society. The Science Institute supports approximately 30 earth scientists, including 15 geophysicists, who would also interact with Dr. Flowers.

0000425花国际研究员奖计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。 该计划的奖项提供了联合研究的机会，以及使用独特或互补的设施，专业知识和国外的实验条件。花与支持12个月的工作与Helgi Bjornsson博士，在冰岛雷克雅未克的冰岛大学科学研究所冰川学的负责人，这个项目的目的是了解冰冠水文的动态，影响稳定和不稳定模式的水流下Vatnajkull，冰岛最大的冰帽，并测试，改进和完善数值模型，为更大规模的调查做准备。 弗劳尔斯博士将使用她开发的冰川水文数值模型作为她博士研究的核心。 她将利用该大学科学研究所提供的关于瓦特纳库尔表面、河床几何形状和水力特性的信息，评估模拟排水结构对目前观察到的排水结构的尊重程度。这个项目代表了第一次尝试描述一个完整的冰川水文计算图片。 这些结果将有利于冰川水力学领域及其对冰川动力学的影响。比约恩松博士被描述为冰岛杰出的冰川学家之一。 他是国际冰川学会的现任副主席。 科学研究所支持大约30名地球科学家，包括15名地球物理学家，他们也将与弗劳尔斯博士互动。
