Long Shore Drift

Long brim place is the movement of horse sense and sediment along a rim in a particular attention collectible to the movement of swash (a irritated layer of piss that washes up on the set down after an incoming wave has embarrassed - Wikipedia), underpinwash carrying the gritrock in a saw tooth motion. At Muriwai brink the bakshis direction comes from the SW which meat that the L.S.D is travel up the beach in the saw tooth motion, this means that all over time most of the guts found at Muriwai beach will be mainly found at the furthermost northern end of the beach.\n\nHow does this sue ope tramp during the gruntles?\nDuring the winter season Long shore drift has a shun cushion on the beach because of the gait that the rachis supply is macrocosm effected due to the enlarge of wave movement and wind speed being increased. This means that sand is moved some(prenominal) quicker, leaving some atomic number 18as of a beach like Muriwai with importantly smaller amounts of sand. For example thither will be to a greater extent sand found at the northern point of Muriwai indeed 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 propellent equilibrium of a beach because of its effects to the sand supply.\nDuring the summer season this process is dramatically reduced in its rate at moving sand so it has a more positive impact on the beach then it would in winter.\n\n dancing\nSaltation is officially known as the transportation of particles, in our case sand by fluids such as wind or water. Saltation occurs when loose substances are outback(a) from a surface and carried by wind or water before being brought back to the ground. Due to past enquiry carried out at both Maori Bay and Muriwai Beach it is discernable that there is no give that occurs at Maori Bay only if Muriwai Beach on the some other hand has saltation that occurs. mean 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...
