Near-bed velocity law and bed shear stress in vegetated flows

Journal of Fluid Mechanics
By generating drag and turbulence away from the bed, aquatic vegetation shapes the mean and turbulent velocity profile. However, the near-bed velocity distribution in vegetated flows has received little theoretical or experimental attention.

Shear Stress And Hydrodynamic Pressure Measurements At Sea Beds

Proceedings OCEANS '83, 1983
Devices to measure the shear stress have been developed earlier by Preston, Vennard, Strauss, and Blau. These instruments are limited to smooth and rigid walls and to cases where the flow direction is known. The differences, however, between measurements of sediment transport and numerical forecasts made it worthwhile to develop a shear stress meter to

Extreme bed shear stress during coastal downwelling

Ocean Dynamics, 2019
The wind-driven circulation of coastal oceans has been studied for many decades. Using a 2.5-dimensional hydrodynamic model, this work unravels new aspects inherent with this circulation. In agreement with previous studies, downwelling-favorable coastal winds create an overturning cross-shelf circulation that operates to mix nearshore water.
