Atmosphere, 2021 The drag coefficient is essential for calculating the aerodynamic friction between air and sea. In this study, we regress a set of relationships between the drag coefficient and the wind speed for different wind ranges using an observational dataset that

A parameterization of the ice‐ocean drag coefficient [PDF]
Journal of Geophysical Research: Oceans, 2011 A parameterization of the ice‐ocean drag coefficient (Cw) was developed through partitioning the oceanic drag force into three components: (1) form drag on the floe edge, (2) form drag on the ridge keel, and (3) skin friction on the ice bottom.

Frontiers in Earth Science, 2022 Bottom drag coefficient is one of the key parameters in quantifying shelf hydrodynamics and sediment transport processes. It varies markedly due to dynamic forcing and bed type differences, so a set of empirical values have been used for beds of coarse ...

DRAG COEFFICIENT OF VEGETATION IN FLOW MODELING [PDF]
Coastal Engineering Proceedings, 2012 Flow through vegetation has a significant impact on sediment transport and ecosystem robustness in the coastal and fluvial environment. Numerical models (Nepf and Vivoni, 2000; Uittenbogaaard, 2003) have been developed to simulate this type of flow. The success of these models depends on proper characterization of the main processes and appropriate ...
