Effects of deglacial sedimentation pulse, followed by incision: A case study from a catchment in the Northern Calcareous Alps (Austria).

Diethard Sanders
In the ‘Giessenbach’ catchment (Northern Calcareous Alps, NCA), a thick sedimentary succession accumulated during to shortly after deglaciation. The catchment is located on faulted and jointed Triassic dolostones. Up-section, the Quaternary succession consists of: (a) redeposited till with index clasts of the Last Glacial Maximum (LGM), (b) pebbly alluvium supplied from the dolostone substrate, (c) fluvial deposits veneering terraces, and (d) large scree slopes. Today, the pre-LGM upstream half of the Giessenbach course is a...
