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 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.

Title: From field to space: multisource data to show how a nature based management can help to cope for sea level rise in the Mediterranean area
Abstract: In Camargue, a coastal wetland area on the border of the Mediterranean Sea, there is a strong dynamic of the coastline retreat with nearly 200 meters since the 1950s. While 2 solutions, a protective solution with dykes or a fallback solution, are being planned, a 3rd one is investigated in this study: a nature-based management. Since 2010, the Conservatoire du Littoral, a public organization that protects coastal areas in France, has progressively purchased 65 km2 of former saltworks. The site hosts large areas of lagoons, Mediterranean salt steppes, coastal dunes and wooded dunes. It was exploited for industrial salt production with major transformations between the 1950's and early 1970's. The restoration of natural flooding patterns integrated in this adaptive management plan has favoured the development the NATURA 2000 habitat called “Mediterranean and thermo-Atlantic halophilous scrubs (Sarcocornetea fruticosi)” that decreased with the development of the saltworks industry from 1856 and the agriculture. In this study we used multi-source data from an interdisciplinary protocol including measurement of sediment sizes, analyses of satellite images and LIDAR acquisitions, and vegetation inventory in the field. From this multi-scale data gathering, we highlight the sediment distribution and flooding periods at the development places of the scrub vegetation on the borders of dunes. This study shows how the interdisciplinarity can help to promote nature-based solutions to face climate change, and how it is important to consider wetland ecological functions in management actions.

Title: A data-consistent model of the last glaciation in the Alps achieved with physics-driven AI
Abstract: 25 thousand years ago, the European Alps were covered by a kilometre-thick body of ice, commonly described as the Alpine Ice Field. Numerical modelling of this glaciation has been challenged by persistent model-data disagreements, including large overestimations of its former thickness. Here, we tackle this issue by applying the Instructed Glacier Model, a three-dimensional, high-order, and thermo-mechanically coupled model enhanced with physics-informed machine learning. This new approach allows us to produce an ensemble of 100, Alps-wide and 17 thousand-year-long (35-18 ka) simulations at 300 m spatial resolution. Unfeasible with traditional models due to computational costs, our experiment substantially increases model-data agreement in both ice extent and thickness. The model-data offset in ice thickness, for instance, is here reduced by between 200% and 450% relative to previous studies. The results yield implications for more accurately reconstructing former ice velocities, ice temperature, basal conditions, glacial erosion processes, glacial isostatic adjustment, and climate evolution in the Alps during the last glaciation. Furthermore, this study demonstrates that physics-informed AI-driven glacier evolution models can overcome the bottleneck of high-resolution continental-scale modelling required to accurately describe complex topographies and ice dynamics.
