International Fellow Awards: Modeling the Spatial and Temporal evolution of Vatnajokull Hydrology

花卉国际研究员奖励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，并利用国外独特或互补的设施、专业知识和实验条件。该奖项将为Gwenn E.Flowers博士提供为期12个月的支持，以便与冰岛雷克雅未克的冰岛大学科学研究所冰川学主任Helgi Bjornsson博士合作。该项目的目标是了解影响冰岛最大冰盖Vatna jkull下稳定和不稳定水流模式的冰盖水文动力学，并测试、改进和完善一个数值模型，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学数值模型，作为她博士研究的核心。她将使用通过大学科学研究所获得的关于瓦特纳库尔表面和河床几何形状和水力特性的信息，以评估建立模型的排水结构与目前观察到的结构相吻合的程度。这个项目是第一次尝试描述冰川水文学的完整计算图景。这一结果将有助于冰川水力学领域及其对冰川动力学的影响。比约恩松被描述为冰岛杰出的冰川学家之一。他是国际冰川学会现任副会长。该科学研究所支持大约30名地球科学家，其中包括15名地球物理学家，他们还将与弗劳尔斯博士互动。

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.
