Swash regime
SpletThe terms swash and backwash collectively refer to the oscillatory motion of the shoreline due to the continuous arrival of waves. They also describe the associated thin lens of water behind the moving shoreline that periodically covers and uncovers the beach face. Splet27. okt. 2002 · The overwash regime features intermittent wave runup events that overtop the dune crest and initiate both seaward and landward water and sediment transport …

SpletRHIGH is lower than DLow, swash regime, the first and least severe impact level, occurs. When RHIGH is lower than DHIGH but higher than DLow (on beaches with a foredune ridge), col-lision regime, the second impact level, occurs. Dune scarping is a typical response under collision regime and is commonly SpletThe storm impact regime is determined as swash regime, and the sand of the beach foreshore is transported offshore by the storm, however, the eroded sand is transported …
SpletSwash climate includes the swash period, speed, turbulence and water move- ment over and into the beach face. The intertidal gradient is the degree of aerial exposure of the sedi- ment surface and the changing moisture content of the sand over the tidal cycle. LARGE-SCALE VARIATIONS Spletvalues are used to classify the beaches according to the coastal storm impact regime as (1) swash, (2) collision, (3) overwash, and (4) inundation. Finally, the limit between each regime is established based on the relation among dynamical and geomorphological parameters. The methodology was applied to the east (exposed beaches) and north
