Division on Geomorphology

President: Daniel Parsons (gm@egu.eu)
Deputy President: Giulia Sofia (giulia.sofia@uconn.edu)

Geomorphology is the scientific study of land-surface features and the dynamic processes that shape them. Besides focusing on the diverse physical landscapes of the Earth, geomorphologists also study surfaces of other planets. Understanding landform history and dynamics, and predicting future changes through a combination of field observations, physical experiments, and numerical modelling is at the heart of geomorphology. The division brings together research on processes that build topography trough e.g. the effects of tectonic forces as well as processes that modify the terrain such as weathering, erosion through running water, waves, glacial ice, wind and gravitational forces. Division members also study the impact of humans on geomorphological processes and investigate how geomorphological knowledge can be applied to solve problems of relevance to societies.

 EGU CampFire - Landscapes Live - Virtual Webinar Series in Geomorphology 

EGU are pioneering a new CampFire concept to bring together the geoscience community across the year inbetween our General Assemblies.  We hope that this will meet the needs of the current pandemic but also help us in our transition to a greener future and ensure that our community better serve the needs of all scientists regardless of international mobility. 

Landscapes Live is the Geomorphology Division's virtual webinar series focused on sharing exciting geomorphology research throughout the international scientific community. You can register for the next webinar, on 26th of November (see below), here:

Autumn CampFire Schedule:

“Appalachian pasts, Arctic futures: permafrost landscape dynamics” - Joanmarie del Vecchio (Penn State University) - Thursday the 5th of November 2020 at 4pm CET.
Abstract: What happens to permafrost landscapes when the climate heats up? Today, high latitudes face amplified warming and permafrost thaw, leading to erosion, carbon release and ecosystem disturbance, and predicting the location and magnitude of such disturbance is a top priority for Arctic communities and climate modelers alike. I argue we can make better predictions by probing sedimentary records from past warming events in unglaciated Appalachia, where permafrost thaw and ecosystem change occurred thousands of years ago and is recorded in sedimentary archives in headwater catchments and bogs. I show how digital terrain analysis in both Appalachia and Alaska, geophysical imaging, isotope and bulk geochemistry and pollen allow me to connect erosion rates and styles to  past climate conditions. 

“Faulting and landscapes – a tribute to Patience Cowie” - Alex Whittaker & Mikael Attal (Imperial College London & University of Edinburgh) - Thursday the 12th of November 2020 at 4pm CET.
Abstract: Patience Cowie inspired a generation of geologists and geomorphologists to understand the linkage and interactions between faulting and landscape evolution. The Italian Apennines, an area of active extension, provided a well-constrained tectonic template that motivated many of her field and numerical modelling contributions. Here we revisit the quantitative insights we have gained from studying the tectonic geomorphology of this spectacular region in the last 15 years, and we take a forward look at some of the key research questions that remain unresolved.

“Exploring the timing, triggering and spatial distribution of landslides along the Cascadia Subduction Zone” - Alison Duvall (University of Washington) - Thursday the 19th of November 2020 at 4pm CET.
Abstract: The last decade has provided unexpected lessons in the enormous risks from great subduction earthquakes: Sumatra 2004, Chile 2010, and Japan 2011 were each devastating, resulting in surprising impacts distinct from shallow seismic events. Similar large-magnitude earthquakes are known to occur on the Cascadia subduction zone, with the potential of rupturing the entire 1100 km length of the Pacific Northwest plate boundary. Because a magnitude 9 (M9) subduction earthquake is well known to have occurred just over 300 years ago, evidence of coseismic landslides triggered by this event might still be present in the landscapes of the Washington and Oregon Coasts. Indeed, the coastal Pacific Northwest USA hosts thousands of deep-seated landslides, yet little is known about their timing or what triggered them. In this talk, I will show our new map of 9,938 deep-seated bedrock landslides in the Oregon Coast Range and explain how we used surface roughness dating to estimate that past earthquakes triggered less than half of the landslides in the last 1,000 years. Comparison of our inventory with other geophysical factors suggests that landslide frequency increases with mean annual precipitation but not with modeled peak ground acceleration or proximity to the megathrust. Our results agree with findings from other recent subduction-zone earthquakes where few deep-seated landslides were mapped, and suggest that despite its proximity to the megathrust, most deep-seated landslides in the Oregon Coast Range were triggered by rainfall.

“Estimating mass loss from pebble shape” - Gabor Domokos (Budapest University of Technology) - Thursday the 26th of November 2020 at 4PM CET.
Abstract: One important question in sedimentology is the mass loss of pebbles due to erosion. In some cases it is possible to track the mass loss process, however, this may not always be the case. We present a mathematical theory which suggests that from measurements of current shape descriptors and some information on the formative process, the original mass of pebbles may be efficiently estimated.

Interview with the Steepest Descent Organizers

The Steepest Descent is a yearly one-day meeting taking place in Vienna, Austria, close to the EGU general assembly. Participants have the opportunity to see a few keynote talks by outstanding geomorphologists and to discuss their posters in a more informal and geomorphology-focused community than at the EGU. Despite its youth, the Steepest Descent Meeting seems to have lost its aura of a niche-event, and it may already be considered as a must for our community. In the team of …
