Huybrechts P, Fürst J, Rybak J, Eisen O (2013) Calibration of a higher-order 3-D ice-flow model of the Morteratsch glacier ... WebAbstract. Alpine glaciers are shrinking and rapidly loosing mass in a warming climate. Glacier modeling is required to assess the future consequences of these retreats on water resources, the hydropower industry and risk management. However, the performance of such ice flow modeling is generally difficult to evaluate because of the lack of long-term … Web23 de nov. de 2010 · We present a flow-band model of glacier dynamics with a Coulomb friction sliding law that is coupled to a model of the basal drainage system by means of subglacial water pressure. The ice-flow model contains “higher-order” stress gradients from the Stokes flow approximation originally conceived by Blatter (1995). greenwood sc fast food
