Abstract: 

In this research, using Hanson and Short method, the various reactions of Mazandaran province shoreline against wind-driven waves and the beach status were determined. First, the kind of hydrodynamic forces governing the beaches were investigated and these beaches recognized as wave-dominated. Then, eight stations along the entire shoreline were selected and waves and sediments characteristics in various depths were investigated employing field measurements, laboratory and calculated data. In this way, the dimensionless fall velocity parameter was calculated in each station and the beach status and its variations with time were calculated. Finally, the obtained data were transferred into the Arc GIS software and the waves dynamic and the mechanism of erosion and accretion in the regarded zone were investigated.
The results showed that the beach status of the central and eastern coasts of Mazandaran province (Neca, Farahabad, Larim, Naftchal, Mazandaran University, Babolsar, Noor stations) is dissipative, and the quantity of dissipation decreases from east to west, discontinuously. Moreover, the beach status of the western part of this province (Nashtarood station) is intermediate.
