Glacial landscapes are constantly transforming in response to past and present climate and environmental conditions, e.g. available debris. Especially due to past and present global warming, rapid changes in these landscapes are observed. These changes are associated with transitions from different processual states : glacial – periglacial – paraglacial, and associated morphologies and landforms, including debris- covered glaciers and rock glaciers which are less understood. To unravel and quantify these past and present evolutions, controls and feedbacks, a broad spectrum of methods are available, including geomorphological mapping, dating, remote sensing, geophysics, numerical modelling, climate reconstruction, field observations and more. This session welcomes contributions related to all these methods, concepts and approaches used to investigate glacial-periglacial-paraglacial landscape evolution, controls and feedbacks. We seek abstracts on topics such as:
• conceptual frameworks of the evolution of glaciated landscapes;
• processual studies of glacial, paraglacial and periglacial landscapes across all temporal and spatial scales;
• transitions of glacial to periglacial or paraglacial landforms, and the role of debris cover within these glacier land systems
• geomorphometry of past and presently glaciated landscapes, debris-covered glaciers and rock glaciers.
• Interaction between debris-covered glaciers and the wider land system, for example, in terms of geohazards, erosion, sediment transport, and deposition.

CR 4.1 Evolution of glacial-periglacial-paraglacial landscapes and debris-covered glaciers Co-organized by GM7 Convener: Johannes BuckelECS | Co-conveners: Adina Racoviteanu, Evan MilesECS, Lindsey Nicholson, Tobias Bolch, Anne VoigtländerECS, Jasper Knight, Darren Jones General structure: - Please note that the order and number of presentations has been changed as some authors could not attend under the circumstances. At first all authors will present the abstracts with displays, afterwards the abstract without displays will be discussed. Please check the adjusted display schedule in the session description or in the uploaded session material. - We will try to stick to the schedule and make sure the session doesn’t end in some chaos! - Convener will introduce the presenter by display #. Presenter who should then briefly introduce their display in a couple of sentences or bullet points. Thereafter, the stage is open for discussion. When the time is up we will move to the next presenter. Please consider using the comment function at the display pages for further discussion until the end of May. First part of our session (Wednesday, 6 May 2020, 08:30–10:15 CEST) Chairpersons: Johannes Buckel, Anne Voigtländer We have 10 displays and 8 abstracts to discuss, respectively. The display will be presented first because a fixed attendance is confirmed by the authors.
