DEVELOPMENT OF IN-SITU MEASUREMENT DEVICE FOR MODEL PARAMETERS OF MUD RESUSPENSION ON SEABED
Development of in-situ device to determine the model parameters for erosion in numerical modeling of bottom sediment transport in coastal areas was carried out. In the present research, two model parameters for erosion, namely, critical shear stress τcr and erosion rate parameter M can be estimated...

| description | Development of in-situ device to determine the model parameters for erosion in numerical modeling of bottom sediment transport in coastal areas was carried out. In the present research, two model parameters for erosion, namely, critical shear stress τcr and erosion rate parameter M can be estimated by the in -situ measurement using the device. In-situ experiment using the device was attempted at 19 sites in Minamata Bay, Japan, in 2019. We succeeded to determine the two parameters through the in-situ measurement effectively. From the comparison between the present result and the results from references, our results are included in the suitable range, but τcr shows smaller and M is higher than the previous researches because of the possibility of generation of fluid mud on the bottom surface in the bay. |
