Section 5.5: Earth Surface Process Modelling

Research approach

In our research group, we develop computer models to simulate the processes responsible for the evolution of the Earth´s surface, such as bedrock incision by rivers and glaciers in mountain ranges, or the slow weathering of rock in low relief continental interiors. In doing so, we provide a framework to integrate field observations and laboratory measurements, and make predictions about places where no data exists or concerning the future evolution of the Earth´s surface.

Our group employs a range of researchers who all share a common interest in computer models, but who are from a variety of research backgrounds, including geology, geophysics and mathematics. We also work closely with colleagues in other sections of the GFZ as well as other German and international research institutions and universities.

Job Posting

We are currently advertising for three Senior Scientists to join the section. The deadline for applications is 31st May 2018. Please feel free to contact us with any queries about the roles.

Further information is available on the GFZ Jobs page.

Section seminars

Several times a year our section hosts seminars which offer scientists the opportunity to present  and discuss their work. 

An overview of past and future seminars is available from this link (opens in pdf format). The list of seminars is updated regularly, so make sure to check back!

EGU annual meeting 2018

On April 8-13, most of the members of Section 5.5 attended the annual meeting of the European Geosciences Union in Vienna.

The diversity of sessions provided something to every taste: members of the section were seen attending talks and posters on geomorphology, hydrology, geoinformatics, glaciology, paleontology, space science ... After all, one of the advantages of a large international conference is the broad expertise on display. Members of 5.5 displayed their own expertise in the form of poster presentations at the meeting. Most opted for a traditional format, while Benoit Bovy and Kim Huppert had to deal with the particular opportunities as well as challenges of an interactive poster presentation called PICO®. The presenters' experiences varied widely, but all were generally happy with their own work and the interesting feedback received.

Towards the end of the meeting, everyone enjoyed catching up with Frederic Herman's group from University of Lausanne: there were plans to be made for the group visit coming up in June. Check back in a couple of months to see if any came to fruition!

Group Retreat, Belgium, October 2017

For our first group retreat, we spent a great weekend at the end of October in the Belgian Ardennes! We enjoyed walking across lovely landscapes such as the (wet) Haute-Fagnes plateau and the valleys of Semois and Ninglinspo, where we saw some interesting geomorphological features. We also visited the city of Liège as well as the Bastogne War Museum that immersed us into the Battle of the Bulge. Of course, we also enjoyed local food specialities and fine Belgian beers!


Congratulations to Jessica Stanley and Audrey Margirier, who have been awarded a Humboldt Fellowship and a DAAD PRIME Fellowship respectively. Jessica´s Humboldt Fellowship, investigating the longterm uplift and erosion of southern Africa, began in September, while Audrey will complete a further year of research at the GFZ before moving to the University of Arizona to study with Professor Peter Reiners.  Following her year in Arizona, where she will be researching triggers for uplift and exhumation in the Ecuadorian Andes, Audrey will return to Potsdam for a further six months´ research with Professor Manfred Strecker at the University of Potsdam. 

Jessica writes, "Continental plateaus are complex manifestations of the interaction of tectonic, deep earth, and surface processes. Their formation mechanisms are not fully understood, in part because the timing and pattern of plateau uplift of is often not well known. Surface uplift is difficult to detect directly in the geologic record, but topographic uplift generally triggers an erosional response. I propose to take advantage of this relationship to constrain plateau uplift. To do this, I will constrain a landscape evolution model inversion scheme with a variety of erosion history data. This will allow me to systematically test a range of parameters to understand which uplift histories are best able to replicate the observed data, taking advantage of observations that record the erosion history on a range of spatial and temporal scales."

Audrey writes, "The growth of the Ecuadorian Andes In Ecuador has been linked to the subduction of the oceanic Carnegie Ridge. However, recent studies have suggested that a crustal sliver in western Ecuador escaping northward along the Pallatanga strike-slip zone may have influenced topographic growth in this region. The project aims at deciphering the roles of oceanic ridge subduction and/or or strike-slip motion in prompting the growth of the Ecuadorian Andes, by  performing low-temperature thermochronology to assess uplift and exhumation associated with the Pallatanga Fault, followed by an inversion of landscape evolution using thermochronological data to constrain uplift rate, timing and location of the uplift and test the roles of the ridge subduction vs. topographic growth related to strike-slip faulting."



Happy Birthday Section 5.5!

It´s hard to believe, but our section is now a whole year old. In the course of just a year it´s grown from a tiny team of three to a flourishing research community of 12 (soon to be 13) staff. Since June this year, we´ve welcomed Dr. Ruohong Jiao, Dr. Audrey Margirier, Dr. Dominik Schneider, Igor Lisac and Erik Tamre into our group while bidding farewell to Dr. Eric Deal. In November we´ll be joined by Dr. Katherine Kravitz who´ll be working at the fascinating (and hereto little explored) interface of biology and geomorphology.
