Yatsu landscapes are characterized by the valley-floor paddy fields and valley-slope woodlands. The sequences of valley floor and valley-slope land-use changes were identified using grid-cell data from 1950s, 1970s and 1990s. The results enabled the

In this paper, we proposed a method of calculation to predict quantitatively the on-offshore sand movement and the wave deformation on a wave-current coexistent system by assuming a river mouth. And the calculated results were compared with the exper
