AbstractFishermen and citizens of the Nakatsu City fear effects of expansion work of the Nakatsu Port on the erosion of the Nakatsu Intertidal flat. However, Even the fact of erosion/deposition of the intertidal flat has not been cleared yet. In this study, field observations of bottom survey and of sediment discharges from the Yamakuni River were conducted in order to investigate the erosion/deposition of the flat and the mechanism of morphodynamic changes. Numerical simulations were also conducted in order to forecast the morphodynamic change and to propose the effective countermeasures to maintain the intertidal flat.
