PhD-Thesis: Quantifying sediment storage in the Upper Rhone Valley, Switzerland

In my PhD I focus on the storage of coarse-grained sediment along the flow path from rockwall source regions to large sedimentary sinks in major alpine valleys. In the field, I investigate the spatial distribution and the volume of small scale sediment storages (e.g. talus and debris flow cones) on the regional and local scale respectively. These results are then used to estimate the sediment stored in the headwaters of a large scale drainage basin, the Upper Rhone basin, Switzerland (> 5400 km²), using a statistical modeling approach. The aim of my research is to close the gap between detailed small scale studies and large scale sediment budgets.


Research interests:

  • sediment storage and dynamics in high-mountain environments
  • sediment connectivity and hillslope coupling
  • mountain geomorphology
  • application of geophysical methods (ERT and GPR) in geomorphology
  • geomorphometry
  • surface exposure age dating (10Be)
