Abstract

A predictive theory for the formation of ripples under sea waves is presented for a sandy bottom characterized by a large grain-size distribution. The theory is based on a linear stability analysis. The conditions for the amplification or decay of bottom perturbations are determined and the experimentally observed sorting effect due to the presence of the bedforms is modelled. A comparison between the experimental data available in literature and the present results is attempted.
