This proposal seeks for funding to complete the research of PhD candidate M. Dürst Stucki. We need financial resources to support the PhD student for 8 months with a salary, and for attending approximately two national meetings and one big international conference. We propose to search for the potential controls on the formation of overdeepened valleys in the Alps and its northern foreland during LGM and earlier glaciations by restoring a high-resolution map of the rockhead (i.e. the top of the bedrock) for the entire area north of the Alps. The map will be analyzed for key morphologic properties that are indicative of distinct erosional mechanisms by glaciers including: (i) erosional carving by changes in the pressure gradients of the subglacial meltwater, (ii) glacial scouring in response to variations of ice flow velocities that are modulated by subglacial water pressure gradients, or (iii) glacial erosion controlled by basal shear forces only. We will proceed by compiling stratigraphic information extracted form: free drill databases of various sources (cuttings, dynamic probing) derived from tens of thousands of drillings, seismic profiles (if available), observations during the building of constructions, previously published reports about the possible course of the bedrock surface, and already existing bedrock surface maps. The rockhead map will then be reconstructed by subtracting the thicknesses of the Quaternary deposits from the elevations of the modern surface. We will explore this map for possible relationships between morphologic features and patterns of rock mass strengths, elevations of the ELAs, and configuration of the contributing areas. These parameters either influence the erosional potential of glaciers through variations in the erosional resistance of bedrock, pressure gradients of the subglacial meltwater, and/or ice flow velocities, respectively. We anticipate that our analysis will yield in an improved understanding about the mechanisms of glacial scouring as it will be based on stratigraphic information of tens of thousands of shallow drillings.
