A seminar by Marion Parquer at ENSG, Nancy, room G201

On Friday 8 of December, 1:00 pm.

Abandoned meander loops during the channel evolution are valuable witnesses of the paleo-trajectories of the system. The reconstruction of the complete history of the main channel is crucial for the understanding of ancient or modern channelized systems.

However, such information can be lost after the reworking of the channel belt through migration or avulsion processes after the loop cutoff. Moreover, deep structures can be difficult to observe on seismic images.

To overcome these difficulties, we propose to stochastically simulate meander loops inside the meander belt. This simulation is done for a given time step with constraints on the position, orientation and dimensions of the abandoned loop in order to fit the meandering context.
