WebOther articles where longshore current is discussed: mineral deposit: Beach placers: …flow of water, called a longshore drift, occurs parallel to the beach. Such a current can produce a beach placer. Beach placers are a major source of ilmenite, rutile, monazite, and zircon. They have been extensively mined in India, Australia, Alaska (U.S.), and Brazil. WebDeposition. All this erosion means radically altered landscapes. But because the Earth is a closed system, it also means that material is being dumped elsewhere. Once the ice, wind or water carrying eroded material away from its original location no longer has the energy to transport it further, the process known to geologists as deposition occurs.

WebTechnique 4 – Measuring the impact of groynes on longshore drift. A popular fieldwork technique is to investigate the impact of groynes on longshore drift. The difference in height of the beach either side of the groyne will give an indication of the effectiveness of groynes in trapping material being transported by longshore drift. WebLongshore drift from longshore current is a geological process that consists of the transportation of sediments (clay, silt, pebbles, sand, shingle) along a coast parallel to the shoreline, which is dependent on the angle of incoming wave direction. Oblique incoming wind squeezes water along the coast, and so generates a water current which moves …
WebIn fluvial geomorphology, a debouch is a place where runoff from a small, confined space emerges into a larger, broader space. Common examples are when a stream runs into a river or when a river runs into an ocean. Debouching can generate massive amounts of sediment transport. When a narrow stream travels down a mountain pass into a basin, an ...
