Abstract: Water now through the vein structure of temperate ice is described as Darcian flow in which the pressure gradient is determined from vein size and overburden pressure . A solution method for the resulting equation is given and two special cases are considered. For steady flow the equilibrium vein size is a function of depth and. by neglecting the effects of diffusion, it is shown that flow perturbations introduced at the surface propagate downward at a constant speed. These perturbations propagate so slowly that even annual surface fluctuations of flow may be eliminated by diffusion before reaching the bottom of the glacier.
