Morphology of glacial accumulation landforms in two Bohemian Forest cirques

Abstract

Morphological phases of moraines from north-oriented valleys are known in the Bohemian Forest. Detailed data from south-oriented valleys are still missing. This paper presents morphological phases of moraines from two valleys. Glacial landforms were defined by an accurate digital elevation model (DEM) and verified by field mapping. The extent and internal structure of the selected glacial landforms were refined by geophysical profiling. We have described 8 morphological phases of moraines in the Großer Schwarzbach cirque locality (south orientation) and 4 morphological phases of moraines in the Kleiner Rachelbach cirque locality (north orientation). In the north-oriented valley, the number of morphological phases of moraines corresponds to other north-oriented sites in the Bohemian Forest. In the south-oriented valley, the number of morphological phases of moraines exceeds the number of morphological phases of moraines in the north-oriented sites in the Bohemian Forest.
