Testing biotic controls on erosion and sediment transport in the Chilean coastal cordillera with cosmogenic 10Be-derived erosion rates and a shear stress-based river incision model

To examine the influence of biota on erosion and sediment transport in the framework of a threshold-stochastic stream power model of river incision and test the hypothesis that biota, the characteristics of soils, and vegetation, influence river incision primarily by modulating the magnitude-frequency distribution of flood events.

You will conduct field work in Chile and combine catchment-average erosion rates, based on cosmogenic radionuclide abundances in river sediments, with analysis of discharge data and results from an ecohydrological model to calibrate and test a threshold-stochastic stream power model of river incision. PI: Jun. Prof. Dirk Scherler (GFZ section 3.4), co-PI: Dr. Eva Nora Müller (University of Potsdam)

The EarthShape project (www.earthshape.net) will explore how biologic processes form soil, influence topography, and thereby shape the Earth surface. You will work in a consortium of 13 interdisciplinary projects comprising 17 new PhD students encompassing the fields Geology, Ecology, Soil Sciences, Geography, Microbiology, Geophysics, and Geochemistry. EarthShape research will be conducted at four study sites within in the Chilean Coastal Range that features one of Earth’s most spectacular vegetation gradients and is controlled by climate ranging from hyper-arid to humid temperate. It is a natural laboratory to study how biology and topography interact. You will be trained in interdisciplinary methods and conduct joint field work and events.

You can expect a very diverse and challenging job in an international work environment that is characterized by exciting research projects. The compatibility of work and family life is of particular concern to the GFZ. Therefore, it offers the opportunity for flexible working time and workplaces. Moreover, there is a kindergarten located on the research campus.

The GFZ is a partner with Geo.X (www.geo-x.net), and as such it is well connected with other geoscience institutions in Potsdam und Berlin. Geo.X forms the largest regional cluster of geoscientific expertise in Europe and offers excellent opportunities for cooperation and development.
