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 # @unisalzburg.bsky.social

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. esurf.copernicus.org/articles/12/...

Channel concavity controls planform complexity of branching drainage networks

Abstract. The planform geometry of branching drainage networks controls the topography of landscapes and their geomorphic, hydrologic, and ecologic functionality. The complexity of networks' geometry ...

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! Old but gold!

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!

doctoral project funded (10 PhD positions :-))

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

Jörg Robl @joergrobl.bsky.social · 07/03/2024

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.

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! 🤩🤩🤩

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).

I defended my PhD almost 20 years ago. Today, my former PhD supervisor (Kurt Stüwe) visited me and we moved the project meeting to my beloved backyard :-). 20 years later we still enjoy working on projects together as friends - that's what good mentoring is all about.

Strong pleas at the Falling Walls Science Summit in Berlin by Johan Rockström @pik-potsdam.bsky.social and Lars Peter Riishøjgaard WMO: it's time to push the panic button and act to bring CO2 levels down. All regulations are in place, but have not impacted CO2 increase. Can COP28 move to mitigation?

I am still positively surprised at how well the debris flow code works, which I wrote 15 years ago as part of my work in a geological office. In today's course we use model results to determine the potential impact of debris flows on infrastructure. #Teaching at the University of Salzburg ⚒️

Jörg Robl @joergrobl.bsky.social · 05/11/2023

In tomorrow's GIS course we will be working on alpine natural hazards (e.g. rockfall) and impact analysis. The exercise serves as preparation for the dimensioning of protective structures for infrastructure in alpine areas - a typical task for our graduates in their future everyday work. 🧪 ⚒️

Fantastic outcrop of the Oberalm Fm. with marls and clay-rich beds (background sedimentation), and calcareous turbitites. The iconic peaks of the Barmsteine - landmark of my hometown - were formed due to the resistance of the thick, almost vertical turbitite beds to erosive surface processes.

Oberalm Fm: gray layers are marls and clay rich limestone, light layers are calcareous turbitites (Barmstein limestone)

It is often the unimpressive rocks that mark major changes in the evolution of life on Earth. Embedded between the Middle and Upper Triassic carbonate platforms, the fine-clastic Carnian sedimentary rocks, a few meters thick, bear witness to a global climate change: the Carnian pluvial event. ⚒️

Vacation and rainy weather - finally time to deal with the wonderful paleotopography data from Scotese and Wright (2018) (www.earthbyte.org) as part of an outreach project. An impressive way to explain the origin of the Upper Triassic and Jurassic rocks in the Taugl catchment (Eastern Alps) ⚒️.

Jörg Robl @joergrobl.bsky.social · 29/10/2023

I become aware of the deep time at the sight of tropical, Upper Triassic carbonate platforms, which today form almost 3000 m high mountains covered by melting 😭 glaciers. What are in comparison the 100 years, which we participate in the earth history - our impact is already huge ⚒️.

I am currently working on an outreach project for a local museum that is preparing a special exhibition for an alpine catchment. I can't stop looking at the digital elevation model of the catchment. LiDAR is just cool.

It takes a bit of effort to cycle to work in the dark. But often you are rewarded for it: sky in flames over the Salzach River.
