Effet dispersif de la loi d'Exner menant à l'équation de Benjamin-Ono : ondulations d'un sol meuble Exner's law dispersive effects leading to Benjamin-Ono equation: waves over an erodible bed

The flow over an erodible bed is revisited supposing that the flux of sediments is proportional to the slip velocity of the potential flow. This gives a linear Benjamin–Ono equation which is numerically solved, this solution is favorably compared to
