Wave Effects on Mega Ripples and Objects on a Sandy Seabed

Abstract

Our general goals are to advance the hydrodynamics of waves, currents and the two-phase dynamics of sediment transport in coastal seas. An important part is to gain physical understanding of the physics and to enable quantitative prediction of the seabed evolution near the shore. The nearshore morphology includes features of a wide range of length scales: from the entire beach to sand bars and down to sand ripples. The mechanisms may differ over different scales, and may also be intertwined. This proposal focusses on the quantitative prediction and modeling of the formation of mega ripples on a sandy seabed under sea waves, with and without the presence of solid objects such as mines.
