  • The distribution and thickness of pleistocene periglacial cover-beds depend on different relief parameters, the petrography of the underground and the development of the landscape. These dependences are the basis to model the potential distribution
  • and thickness of the cover-beds for the mesoscalic area of the northern Eifel. The results of the model show a potentially larger thickness and distribution in areas with less uplift and a larger distance to the receiving stream. The approach presents
