Abstract

The natural sediment bypassing of river mouth is difficult to determine due to the hydrodynamic complexity in that area. The sediment bypassing of river mouth is one component which important to know and have influence to the behavior of surrounding shoreline. The sediment budget method is applied to determine the sediment bypassing in Nanakita River mouth Sendai Miyagi by using the best known estimated data in that area. The results reveal the existence of sediment bypassing and the role of river mouth to supply sediment to the system. The blocking effects of river mouth to the long-shore sediment transport also indicate in this result. This is important when applying the shoreline change model in the river mouth area.
