| Research Abstract |
A new sediment transport numerical model was developed to unravel environmental problems in Ariake Sea. The model treats grain size fraction and bottom sediment layers. The model was developed as vertical 1-dimensional model and then adopted to FVCOM as 3-dimensional model. The source code was distributed online.3-dimensional erosion property mapping of Ariake Sea was also conducted. The result is applied to the model and the model reproduced the sediment dynamics well.
