Outline of Final Research Achievements

In this study, is discussed to generating of excess pore water pressure induced by free surface flow by the movable bed experiment and exact theory. As a result, seepage flow in the ground surface was generated by free surface flow and the excess pore water pressure was generating induced by differential of velocity in seepage in extreme surface of ground. Therefore, we confirmed that generating the excess pore water pressure in extreme surface of ground was influenced by seepage flow by compared by an experimental result and exact solution.
