SpletDistance between adjacent maxima or minima of a wave. Periodic wave: Wave that repeats over time and space. Also called a continuous wave. Crest: Highest point on a transverse … Swash, or forewash in geography, is a turbulent layer of water that washes up on the beach after an incoming wave has broken. The swash action can move beach materials up and down the beach, which results in the cross-shore sediment exchange. The time-scale of swash motion varies from seconds … Prikaži več Swash consists of two phases: uprush (onshore flow) and backwash (offshore flow). Generally, uprush has higher velocity and shorter duration than backwash. Onshore velocities are at greatest at the start of the uprush … Prikaži več The swash zone is the upper part of the beach between backbeach and surf zone, where intense erosion occurs during storms (Figure 2). The swash zone is alternately wet and dry. Infiltration (hydrology) (above the water table) and exfiltration (below … Prikaži več It is said that conduct of morphology research and field measurements in the swash zone is challenging since it is a shallow and aerated environment with rapid and unsteady swash flows. Despite the accessibility to the swash zone and the capability to … Prikaži več Cross-shore sediment transport The cross-shore sediment exchange, between the subaerial and sub-aqueous zones of the beach, … Prikaži več The swash zone is highly dynamic, accessible and susceptible to human activities.

SpletSWASH is a general-purpose numerical tool for simulating unsteady, non-hydrostatic, free-surface, rotational flow and transport phenomena in coastal waters as driven by waves, … Splet01. nov. 2007 · On steep slopes, a significant proportion of short wave energy contributes to drive swash motions and individual swash events driven by short waves become more significant. The low-frequency component of the swash excursion reduces with an increase in bottom slope irrespective of the mean frequency of the incident wave groups.
