What is it about?
The study by Doré and Coco explores numerical modeling of subaqueous dune saturation, focusing on how dune profiles change and how saturation is provoked. They use a 2-D Reynolds-averaged Navier-Stokes model to investigate the physical processes, revealing that saturation is caused by a shift in the maximum suspension transport downstream of the crests.

Why is it important?
The study is important from a fundamental perspective as it provides a detailed description of the mechanisms behind the stabilization of subaqueous dunes and how the dimensions of dunes at equilibrium are determined.
Perspectives
This study opens up important perspectives on the mechanisms that need to be described in a three-dimensional morphodynamic model.
