Geomorfologie Hřebenů v Brdech

Abstract

4 ABSTRACT The main aims of presented study about the geomorphology of the Hřebeny Ridge in Brdy Mts. are 1/ the documentation of landform patterns and 2/ the description of main stages of the relief evolution. In opening chapters of the paper, the natural envi- ronments of the Hřebeny Ridge and Brdy Mts. as a whole are characterized. In the fol- lowing chapter, a reflection of the geological structure in present-day landforms is de- scribed. Landform analysis of the studied region related to climate-morphogenetic pro- cesses is presented and detailed geomorphological map (1:10 000) is enclosed. Final part of the study is concerned with main stages of the landform evolution of the Hřebeny Ridge. Field observation and its geomorphological interpretation are compared with earlier regional studies. The presented paper demonstrates that landforms of the Hřebeny Ridge in Brdy Mts. are determined by the geological structure, e.g. by the geomorphological resistance of rocks. Present-day landforms of the Hřebeny Ridge evolved in the Quaternary. Im- portant processes of the landform evolution of the region are connected with the origin of deep river valleys. The landform patterns of the ridge part and its slopes are essential- ly influenced by the Pleistocene cryogenic weathering of rocks as well as very intensive...
