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.

Abstract: Some recent publications suggest that we could use the luminescence signal to document and quantify surface processes, sources and sediment transport (McGuire and Rhodes, 2015; Gray et al.,2018; Sawakuchi et al., 2018; Guyez et al., 2022). In the project to be presented, we use the single-grain post-infrared luminescence (SG-pIRIR) protocol to study sediment transport in floodplains. The single-grain approach is well-suited to study fluvial deposits, which often exhibit a large scatter in the luminescence signal distribution due to heterogeneous bleaching ( zeroing) of grains by sunlight exposure prior to burial. We took advantage of these heterogeneities and used the distribution of luminescence signal as a tool to quantify transport processes. We measured modern sediment samples from the Rakaia and Waimakariri rivers in the South Island of New Zealand. Then, using a numerical model that simulates the successive movement and evolution of the luminescence signal along the river, we were able to well reproduce natural observations for transport distances of sand-sized river particles on the order of 2-10 kilometers and storage times of particles in the floodplains of several decades.
