The Geodynamic developments in the natural coast of the region disrupt the natural, balanced and stable trend of coastal reciprocal behavior which leads to reactions such as sedimentation and local erosion depending on new conditions. These changes will have an adverse effect on the performance of the instrument and the created structures. In other words, the structural characteristics of coastal and marine shoreline in the area have a mutual influence on each other.Geodynamic developments in the natural coast of the region disrupt the natural, balanced and stable trend of coastal reciprocal behavior which leads to reactions such as sedimentation and local erosion depending on new conditions. These changes will have an adverse effect on the performance of the instrument and the created structures. In other words, the structural characteristics of coastal and marine shoreline in the area have a mutual influence on each other. Therefore, the studies on implementation or expansion of coastal and marine structures should investigate the effects on the coastal regions under study. In this research, the total sediment transport rate from different directions was calculated by comparing the Bijker’s (1971) formula, the Van Rijn’s formula and the CERC formula as well as sediment transport rate considering the prevailing characteristics of sea waves, sea currents, fluctuation of Caspian Sea levels, and sediment grading curve. Then, the total sediment transport rate was analyzed using the Wet Lay-up statistical technique (Benny Byat and Patrick,2013).
