Relation Between Water Input, Water Pressure, Surface Speed and Basal Till Deformation, Storglaciaren

这个奖项是为了支持一个研究瑞典北部一个小山谷冰川的项目。该项目的三个目标是：1)建立冰川表面融化速率与气象强迫之间的经验关系；2)建立冰川表面冰下水压与冰川表面流速之间的关系；3)测量冰下坡耕地的应变率、剪切应力和水压，以建立坡耕地变形的本构关系。这项工作的长期目标是建立一个模型来预测冰川运动在日至季节的时间尺度。

This award is for support of a project to study a small valley glacier in northern Sweden, Storglaciaren. The three objectives of this project are 1) to develop an empirical relation between melt rates on the glacier surface and meteorological forcing, 2) to establish a relation between subglacial water pressures and velocities at the glacier surface, and 3) to measure strain rates, shear stresses, and water pressures in the subglacial till in order to establish a constitutive relation for till deformation. A long- term goal of this work is to develop a model to predict glacier motion on diurnal to seasonal time scales.
