AbstractNumerical model of the morphodynamic change of intertidal flats is very important to maintain intertidal flats and construct artificial flats. In this study, three-dimensional morphodynamic model considering tidal and coastal currents, sand and cohesive sediments was developed and applied to the Shirakawa intertidal flat in the Ariake Sea in Japan. From comparisons between numerical and observation results around the rivermouth of Shirakawa River, we could recognize the qualitative validity of the numerical model. Furthermore, the simultaneous simulation of tidal and coastal currents and the importance of mud content on the calculation of morphodynamic change of intertidal flats were shown.
