Abstract

The AA. studied the evolution of dolines in ground ice environment, in a paleouvala of the Hochschwab Mts. (Northern Calcareous Alps, Austria) as well as in laboratory conditions. They measured the ground ice thickness by geophysical methods. They estimated the melting (thinning) speed and the pertinent parameters for ground ice samples at different temperatures in laboratory conditions. After simulating the process, the AA. were able to determine the physical conditions generating the ground ice melting phenomena, and based on this they calculated its melting speed. Due to the air circulation in the karst, the lower level of the ground ice starts to melt and the covering sediment particles fall down. Thus the thinned covering sediments will fall-in and dropout dolines will mould the ground, or the surface may sink by the progress of the melting, entailing suffosion dolines to be generated
