Drag Mechanisms in Flow Over Rough Topography

Abstract

In order to effectively model the coastal ocean, it is essential that we understand how flow over rough topography affects boundary drag. The long-term goal of this work is to develop a physical understanding of oceanic flow along irregular, sloping, coastal topography. By understanding the basic processes of internal wave generation and flow separation we will be able to predict the effects of unresolved bathymetric roughness in numerical simulations.
