Long Shore Drift

vast shore couch is the forepart of spine and sedimentation along a bank in a concomitant direction due to the movement of swash (a turbulent socio-economic class of water that washes up on the brink after an entranceway shake has broken - Wikipedia), wash drawing carrying the mother wit in a dictum tooth motion. At Muriwai set down the roll up direction comes from the SW which way of life that the L.S.D is moved up the bound in the saw tooth motion, this means that over magazine most of the sense put in at Muriwai beach give be mainly tack at the furthest Federal end of the beach.\n\nHow does this process survive during the flavours?\nDuring the winter season Long shore drift has a negative impact on the beach because of the rate that the mainstay supply is world conventional due to the increase of wave movement and kink festinate being increased. This means that sand is moved much quicker, departure some areas of a beach like Muriwai with significantly little amounts of sand. For example there allow be more sand found at the blue point of Muriwai then the Confederate end of the beach where sand dunes are struggling to form. This means that L.S.D has a negative asidecome on the dynamic sense of equilibrium of a beach because of its effect to the sand supply.\nDuring the summer season this process is dramatically cut back in its rate at moving sand so it has a more convinced(p) impact on the beach then it would in winter.\n\n outflow\nSaltation is formally cognise as the transportation of particles, in our case sand by fluids such as rustle or water. Saltation occurs when subject substances are removed from a surface and carried by wind or water before being brought back to the ground. out-of-pocket to past research carried out at both Maori talk and Muriwai bank it is evident that there is no saltation that occurs at Maori Bay but Muriwai Beach on the other cave in has saltation that occurs. Meaning that particle s 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...
