A regional sediment transport model by using RRI model, gRSM and WDM-POM was constructed. By applying the model to Yamakuni River Basin and Nakatsu Intertidal Flat and using field observation data obtained by authors in 2017, the validation of constructed model was conducted, and the estimation of sediment movements due to the flood in 2012 was made. Furthermore, by the estimation of future hyetograph by using the d4PDF data, the forecasting simulation was conducted. In conclusions, the qualitative valication of constructed model was done and the similar mud concentration distributions with numerical and observation results in 2017 were confirmed also in numerical results of 2012. Finary, the future forecasting simulation based on the d4PDF data revealed the similar siltation with the results of 2012 and 2017. Detailed investigation will be conducted in the future work.
