Getting an idea about coastal erosion - the power of waves is insane

Waves as sculptors of the coast ...

Beautiful Asturias

What a fantastic day in my backyard with Benjamin Campforts and highly motivated students from the University of Amsterdam.
Triassic reefs, Pleistocene glaciations, retreating waterfalls, rockfalls, and costs for protective measure in a nutshell.

What might the northern Calcareous Alps have looked like in the LGM? - and what are the links between glaciations and landslides? Here is an ice flow simulation for the Hochschwab massif (hosting the Wildalpen landslide) with the new code from: @hergarten.bsky.social

Are you interested in the evolution of high mountain peaks? Visit me at my talk tomorrow at the EGU in room G2, Session TS 4.2 (17:10 - 17:20). Hope to CU there !

:-) :-) :-) 10 fully-funded PhD positions :-) ::-) :-)

Please forward to anyone who might be interested. We offer 10 PhD positions at the interface of geology, ecology and geography. In particular, I would like to promote subproject 6 (see figure).

Liran Goren just presented her recent work with Eitan Shelef on the links between channel concavity and drainage planform network. This is really elegant and captures the non-recoverable reorganization from wet➡️arid➡️wet climate cycles.

In today's tectonic geomorphology course we discussed Davis' Cycle of Erosion (and differences to the models of Penck & Hack) and computed the hypsometric curves of catchments in the Sierra Nevada (Spain) following the recipe of Strahler, 1953. New ingredients: DEMs, GIS & Matlab!

Discussion open for comments: Old orogen - young topography: lithological contrasts controlling erosion and relief formation in the Bohemian Massif egusphere.copernicus.org/preprints/20...

How does relief evolve in intracontinental mountains, how quickly do they erode and what role does lithology play?

Teaching tectonic geomorphology

doctoral project funded (10 PhD positions :-))

climbing in my backyard

skiing in my backyard

Last week's rollercoaster ride started with endless classes despite a cold, but took a very positive turn with the announcement that our €2.5 million doctoral program had been funded. Back to full health, Salzburg never disappoints on weekends with its great outdoor options!

Just grateful...

What would the world be without mushrooms? Most of the year they are almost invisibly hidden in the ground, but in the autumn forest they reveal their many shapes and colors. Many species are dependent on the substrate, resulting in an exciting relationship between fungi, soil types and bedrock.

Why is geology important to understand the climate of the past and the future and to mitigate the consequences of climate change?

I had great hours discussing these and other questions with students from St. Rupert Gymnasium (Bischofshofen).

Thanks for the photos Paul @pamoe.bsky.social

On invitation of the Rotary Club Bischofshofen, I was given the opportunity to speak to a great audience about global links in the climate system, about different time scales of climate change and their impacts on the Alps. Thanks to @pamoe.bsky.social for this enjoyable evening and the photographs.

One of my favorite views of the Dachstein. Rock climbing in my backyard 🤩.

The Eastern Alps are not the Himalayas, but anyone who claims they are a small mountain range only knows them from maps. A few big turns on the white gold in the middle of nowhere - simply the best! 🤩🤩🤩

Ahhh - how annoying. Command line is not the worst choice. The students will hate you 😅, but some of them realize quite quickly how cool it is and then do great student projects that can sometimes even be published - at least that's my experience.

Today's lecture: Equations are the best friends of geologists. In combination with a few cookies, the diffusion (heat) equation was quite easy to digest for our students 😁.

⚒️

I managed to escape the office and went skiing in my backward 🤩. Being alone in the mountains is always great for generating new ideas and thinking about future projects.

Benchmarking codes is essential to find weaknesses and correct bugs. Finding a setup that works for all codes is difficult because even grids are structured differently (in the picture you can see the quadtree grid from Gerris and our extension for rapid mass movements).

Well, ChatGPT knows the future. You will receive these awards in the next years 🎉
