Alpine river morphodynamics

Alternate gravel bar systems

Context We study here the formation and the evolution of alternated bars systems for alpine gravel rivers that are laterally constrained. More specifically we try to understand how fine sediments (sand and silts) can contribute to this dynamics Scientific issues How do gravel bars forms and evolves? How fine sediments impacts this dynamics? Methods & …

Gravel bar morphodynamics

Scientific issue Here we seek to understand the dynamics of a forced gravel bar in interaction with differenttypes of flood event (natural or flushing), i.e. the evolution of secondary and transverse channels and surface grain size distribution. Scientific questions Effect of the shape of the flood event on the general evolution of a gravel bar …
