Abstract

 Estimation equations for the viscosity of water containing suspended sediment were proposed, and flow fields under a uniform flow and a tsunami were investigated using a numerical model combined with the estimation equations. Numerical results showed that the maximum tsunami force on an onshore structure was affected by the change in the density and viscosity due to suspended sediment, suggesting that it is essential to consider the effects of suspended sediment in assessing the maximum tsunami force.
