This paper was presented at the general meeting for establishment of the society as an invited memorial lecture. The paper involves a review of multiphase flow appearing in civil engineering field.
First of all, the phenomena of multiphase flow in civil engineering are classified in Table 1, and especially features of mudflow in mountains and extremely high concentration flow in Yellow River are introduced as peculiar phenomena of one directional two-phase flows with water and sediment. Secondly sediment transport on the beach and beach deformation by waves are discussed as a typical two-phase flow problem in coastal engineering, and in addition, a pneumatic breakwater using air bubble curtain flow is introduced as an application of two-phase flow with air and water.
