Abstract

A ground water flow model is developed with a special attention to a boundary between the unsaturated region and saturated region, and the combination of the each formula of the 1-dimensional motion, The vertical flow in the unsaturated region and the horizontal flow in the saturated region. The proposed model is apllied to the analysis of the seepage flow into the river embankment and it is verified by the result of the experiment on a large scale model.Finally, the horizontal seepage flow in unsaturated region is estimated based on the distribution of the suction simulated by the proposal model. The horizontal seepage flux in the unsaturated region is small enough to omit against that in the saturated region.
