They also describe the associated thin lens of water behind the moving shoreline that periodically covers and uncovers the beach face.

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.

Splet09. jun. 2024 · The first three storms caused swash or collision regime impacts on the Sallenger scale. Hurricane Teddy was the fourth storm to impact the study area, causing overwash at numerous locations.

Splet01. jan. 2013 · The most widely recognized surface form in the swash zone is the upper-stage plane bed, which is consistent with the near-critical to super-critical flow regime that is characteristic of both swash and backwash. Other bed features observed include parting lineations, rolling-grain ripples, rhomboid ripples, antidunes, and swash marks. Splet03. feb. 2024 · The total below-ground biomass of both annual and perennial plants, including roots, rhizomes and buried shoots, reduced dune erosion under a swash regime. Notably, we show that (1) annual pioneer species offer erosion protection, (2) buried shoots are an important plant component in driving sedimen …

SpletWithin each regime, patterns and relative magnitudes of net erosion and accretion are argued to be unique. The borders between regimes represent thresholds defining where processes and magnitudes of impacts change dramatically. Impact level 1 is the 'swash' regime describing a storm where runup is confined to the foreshore. Splet04. jan. 2024 · In the swash regime, the runup was confined to the beach, which caused foreshore and backshore erosion and transport offshore with recovery of the sediment over a period of several weeks to months. The high tide during Hurricane Irma was 1.95 m, which was still lower than the island’s elevation along the northern section. ...
