Swash on steep and gently-sloping beaches
thesis
posted on 2013-07-01, 13:32 authored by Darren EvansIn the last twenty years, the importance of sediment transport in the swash zone has been established. The
disproportionately high sediment transport rates in this region make its inclusion in general nearshore models vital. As
part of this U.K. Natural Environmental Research Council project (grant number: NERlA/S/1999/00144), high
frequency (8 Hz) measurements were made of the water depth and vertical variations in suspended sediment
concentration and water velocity, using state-of-the-art instrumentation. Further measurements included nearshore and
offshore wave conditions, tidal elevations, wave run-up limits, groundwater variations, sediment grain size
distributions, beach slopes and changes in morphology at time-scales from minutes to weeks. Fieldwork was carried
out on a gently-sloping (tan p - 0.03; d50 ~ 0.27 mm) and steep beach (tan p - 0.09; d50 ~ 0.55 mm). Both experience
similar wave climates which allows a direct comparison between hydrodynamics and sediment transport in the swash
zone....
