The effect of suspended sediment on inundation, run-up, wave pressure, and wave force caused by a black tsunami was investigated using hydraulic experiments with clear water and turbid water containing kaolin as bottom sediment. From experimental results, it was found that tsunami inundation can be locally accelerated in kaolin mixed water. Furthermore, the maximum value of surge-front wave pressure was reduced on average by mixing the kaolin. However, large surge-front wave pressure could occur at high concentration due to the high variability. The maximum value of quasi-steady wave pressure increased proportionally to an increase in the apparent fluid density due to the kaolin.
