Abstract

Capillary barrier is the simple soil layer system which is composed of the fine soil (sand) layer underlain by the coarse soil (gravel) layer. The capillary barrier soil was constructed in the natural sand slope, and the volumetric moisture contents in the soil were measured together with precipitations for about four months. Soil moisture changes in the gravel layer were compared those in the sand layer. An excellent divergence of infiltration water along the tilted interface between the soil layers was confirmed. The percolation or breakthrough of the water flow along the interface into the gravel layer was also observed. The divergence length of the capillary barrier where the breakthrough occurs was estimated and compared with the observation.
