Ripple Morphodynamics in Wave-Current Boundary-Layer Flows.

摘要

The long-term goal of our research is to improve our understanding of ripple morphodynamics in wave-current, boundary-layer flows. Our main focus is on the study of sediment transport in oscillatory boundary layers in the presence of unidirectional currents and the associated bed morphology (i.e. 2D and 3D ripples). To this end, both wave-induced and wave-current-induced oscillatory flow conditions are simulated in a wave-current flume and in a Large Oscillating Water Sediment Tunnel (LOWST) built and equipped with an ONR grants DURIP Awards N00014-01-1- 0540 and N00014-06-1-0661.
