| Research Abstract |
This study has conducted the experimental, theoretical and numerical investigation of the transport of soil particles caused by seepage flows. The experimental results showed that the velocity of soil particles transported by the seepage flows is predictable from the equilibrium of the seepage force, exerted onto the soil particles, and the external forces. This important fact for predicting the transport of the soil particles has been verified by the theoretical and numerical analysis. The numerical analysis is expected to be applicable to the variety of phenomena, such as the seepage erosion.
