Advection Distance of Water Droplets in Strong Winds

Abstract
As part of a study on wind effects on runup and overtopping of coastal structures, advection distances for water droplets of various sizes were measured in a wind/wave flume. The study found that advection distances were considerably greater than would be expected from wind forces acting on spherical droplets. Flattening of the windward face of water droplets from splash and spray in the presence of strong wind was found to increase the drag of droplets in this study and possibly add a lifting force, thereby increasing the distances droplets were carried. Results of this study indicate that splash and spray may be carried over a coastal structure considerably farther than may be expected, which in turn may contribute to higher overtopping rates.
