Landscapes Live

EGU-GM Online Seminars in Geomorphology

Landscapes Live is a weekly online seminar series freely accessible to the international scientific community interested in various aspects of geomorphology. Our talks take place on Zoom every Thursday, starting at 4pm time of Paris/Berlin/Amsterdam. Check your local time here.

Landscapes Live is affiliated to the Geomorphology (GM) division of EGU and contribute to develop its virtual activities. Indeed, EGU is pioneering a new CampFire concept to bring together the geoscience community in between General Assemblies. We hope that this helps us in our transition to a greener future and ensure that our community better serve the needs of all scientists regardless of international mobility.

Unravelling the dynamics of debris flows on Earth, Mars, and beyond

Understanding the dynamics of debris flows is important for mitigating hazards on Earth, but at the same time helps us reconstruct the present and past environmental conditions on planets, moons, and asteroids. In this talk I will summarize how we have used physical-scale experiments to 1) unravel controls on debris-flow dynamics, deposit morphology, erosion processes, and fan avulsion mechanisms, 2) decipher how sublimating ices can fluidize debris flows in the absence of liquid water in the thin atmospheres of extra-terrestrial bodies recreated in large vacuum chambers, and 3) determine how gravity affects the dynamics and mobility of debris flows under reduced and enhanced gravity, simulated with parabolic flights. On top of giving insights in the dynamics of debris flows on Earth and beyond, this talk will showcase the power of physical-scale experiments in understanding planetary surfaces, particularly when combined with field observations, numerical modelling, and remote sensing.

Persistent water cycles after Martian floods

Early Mars experienced a wet climate. Low-lying impact craters gathered water, forming lakes. When water levels surpass the crater boundary, lakes can breach and trigger floods that release large volumes of high-energy water. Whether canyon erosion reflects a single breaching flood or sustained post-flood outflow remains unresolved, despite its implications for constraining early Martian water cycles and the potential for lakes to support life. By combining topographic observations on Mars with flood erosion constraints on Earth, we demonstrate the majority of open-basin lakes on Mars (146 out of 200) experienced post-flood outflows (i.e., continued water flow after the initial breaching flood), with total water volumes 55 times greater than initial floods. Such volumes required tens to hundreds of outflow events, indicating that early Mars maintained persistent hydrological cycles over cumulative timescales of millions of years.

Understanding physical landscape effects of climate change: how much do we know, and what are we doing about it?

Today, climate change is affecting virtually all terrestrial and nearshore settings. How well do we understand the physical landscape effects, and how have planning and economic sectors responded so far? This presentation will discuss the challenges of identifying and measuring climate-driven physical landscape responses to modern warming and its associated hydrologic shifts. Challenges include short, incomplete data records, land use and seismicity masking climatic effects, biases in data availability and resolution, signals dominated by individual extreme events, and signal attenuation in sedimentary systems. Despite such challenges, the scientific community has important opportunities to learn from historical and paleo data, to select especially informative study sites, and to learn also from studies producing null results. Fortunately, our knowledge base in these subjects is growing rapidly, leading to substantial progress in protecting communities physically and financially. Knowing that climate-driven sedimentary and geomorphic changes influence human health and safety, infrastructure, water–food–energy security, and economies, we will examine examples of how those effects are being incorporated into planning and design today.
