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 … Prikaži več The swash zone is highly dynamic, accessible and susceptible to human activities. This zone can be very close to developed properties. It is said that at least 100 million people on the globe live within one meter of mean sea level. Understanding the … Prikaži več • Beach cusp • Beach nourishment • Coastal management • Longshore drift • Sea wall • Sediment transport Prikaži več Cross-shore sediment transport The cross-shore sediment exchange, between the subaerial and sub-aqueous zones of the beach, is primarily provided by the swash motion. The transport rates in the swash zone are much higher compared to the … 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.

SpletOn the other hand, constructive waves, predominant in calm weather, have a weak backwash and a strong swash, meaning the waves bring and deposit sediments to the coast lines. Wave processes are an important factor influencing the rate of coastal recession as depending on the climate, the waves could significantly impact the coastal … SpletA swash aligned coastline: directly faces prevailing wind; wave fronts approach it aligned parallel to the coast; swash aligned beaches often exhibit well-defined berms; A drift aligned coastline: aligned at an angle to the prevailing wind direction; wave fronts approach the coast at an angle, meaning there is transport by longshore drift Spletverb (used without object) to splash, as things in water, or as water does: Waves were swashing against the piers. to dash around, as things in violent motion. verb (used with … histidine biosynthesis in plants
