Abstract :

Beaches fringe about 40 per cent of the world’s coastline, and generally consist ofunconsolidated deposits of sand and gravel on the shore. More than half the world’spopulation lives in coastal regions, and many people visit the coast frequently. Beaches havealso formed along the fringes of coastal lowlands. In Iran, the river and coastal systems areone of the most important factors in the location of cities, network connections, commerce,tourism, agriculture and areas of industrial development and have high population density andhave high population density. Beach systems deal with the interactions between beaches andthe processes (waves, currents, tides and winds) that work on them. Case Study at coordinatesof geographical longitude of 51,ْ 30,َ and 00 up to east 52,ْ 45 and 00 and geographicallatitude 36,ْ 18,َ and 55 up to north 36,ْ 44,َ and 00 with an area of 2068.57 square kilometers inNorth of Mazandaran Province is located. The main purpose of this paper is to theIdentification and morphological classification coastal zones used Shepard Classificationmethod, from Nowshahr to Babolsar. Thus, topographic maps and geology, satellite imageryand geographical information system software in Arc GIS and several field visits fromlandforms, has been used. The main purpose of this research is to morphological classificationof coastal zones from Nowshahr to Babolsar using Shepard classification method. Thisresearch is based on the satellite imagery (Landsat, sensors: TM & ETM+, IRS), fieldobservations geological and topographic maps and GIS information. Results of this study,show that the most dominate part of region is covered by Alluvial Plain (with: 42.8%),Pediplain (or Pediment) (with: 16.7%), Lowlands (11.85%), & Flood Plain (9/6%).
