9321350 Harbor This award is for support for a project to use a finite element model for cross-sectional flow to constrain sliding and flow laws for the Haut Glacier d'Arolla (Switzerland). By varying sliding law exponents, the piezometric surface form and position, and the pattern of basil friction it will be possible to constrain the range of conditions that yields velocity fields consistent with empirical data. This work takes advantage of a unique chance to test and refine the general sliding law, and an opportunity to explicitly examine spatial variations in sliding in the context of detailed information on the temporal and spatial development of the glacier's hydrologic system. Although this work will be based on data collected in a mid-latitude alpine area, the results will be of direct relevance to polar glaciology because they can also be applied to glaciers with temperate (warm based) areas in polar regions. ***

9321350 Harbor该奖项用于支持一个项目，该项目使用横截面流动有限元模型来约束Haut Glacier d'Arolla（瑞士）的滑动和流动规律。 通过改变滑动律指数，测压表面的形式和位置，以及罗勒摩擦的模式，它将有可能限制的条件范围，产生与经验数据一致的速度场。 这项工作利用了一个独特的机会来测试和完善一般的滑动规律，并有机会明确检查在冰川水文系统的时空发展的详细信息的背景下，滑动的空间变化。 虽然这项工作将基于在中纬度高山地区收集的数据，但其结果将与极地冰川学直接相关，因为它们也可以应用于极地地区温带（温暖）地区的冰川。 ***
