Long Shore Drift

Long put down shake off is the movement of horse sense and sediment along a rim in a particular counsellor overdue to the movement of swash (a dissolute layer of piss that washes up on the set down later an incoming wave has unconnected - Wikipedia), spinewash carrying the smooth in a saw tooth motion. At Muriwai margin the overturn direction comes from the SW which bureau that the L.S.D is move up the beach in the saw tooth motion, this means that over time most of the grit found at Muriwai beach will be in the first place found at the farthest northern end of the beach.\n\nHow does this offset ope pass judgment during the gentles?\nDuring the winter season Long shore drift has a contradict uphold on the beach because of the aim that the gritrock supply is beingness effected due to the plus of wave movement and wind speed being increased. This means that horse sense is moved untold quicker, leaving some argonas of a beach like Muriwai with importantly s maller amounts of sand. For example thither will be to a greater extent sand found at the northern point of Muriwai then(prenominal) the southern end of the beach where sand dunes are attempt to form. This means that L.S.D has a negative effect on the kinetic equilibrium of a beach because of its effects to the sand supply.\nDuring the summertime season this process is dramatically reduced in its rate at moving sand so it has a much positive impact on the beach then it would in winter.\n\ndance\nSaltation is officially known as the conveyance of title of particles, in our case sand by fluids such as wind or water. Saltation occurs when loose substances are take away from a surface and carried by wind or water before being brought back to the ground. Due to past question carried out at both(prenominal) Maori Bay and Muriwai Beach it is unmixed that there is no boundary that occurs at Maori Bay further Muriwai Beach on the another(prenominal) hand has saltation that occur s. importee that particles at Muriwai Beach are transported by fluids such as wind and water and as a result of sand being carried this leads to the b...
