Popis:	Numerical simulation of suspended sediment concentration in the Ariake Sea was conducted applying erosion property mapping. The result was compared with a 1-tidal-cycle field observation and the model reasonably reproduces temporal variation of Secchi depth and suspended sediment concentration profile in the head of the Ariake Sea. However, significant Secchi depth decreases during ebb tide off Chikugo & Hayatsue river mouth were not reproduced in the model. It suggests that it is necessary to resolve the tidal channel of these rivers for further improvement of the model.
