Abstract

Yokosuka Coast in Miyagi Prefecture is 2km long sandy coast, bounded by the Kitakami River mouth and Nagatsura-Ura tidal inlet. The coast had been stable more than several decades, and had been utilized as a public bathing beach by local people. In recent years, however, very severe erosion occurred along the coast. In this study, mechanism of recent erosion of Yokosuka Coast is investigated by analyzing long-term topographical maps as well as aerial photographs. The main conclusion in the present study is that the sediment transported to the mouth of Kitami River has been flushed during a big flood in 2002, large amount of which deposited in deep sea area and can not move back to shallow area to form the sandy coast.
