内容記述タイプ Abstract
内容記述 Capillary barrier is the simple soil layer system which is composed of a fine soil (sand) layer underlain by a coarse soil (gravel) layer. Water which infiltrates into the soil can be well retained above the interface between the sand and gravel layers because of the difference in hydraulic properties of the soil layer materials. In the case of a tilting interface, the water retained moves downward along the interface between the soil layers. This waterproof by the capillary barrier of soil with the tilted interface decreases rainwater infiltration into the deeper soil, and keep a soil slope stable. This special and attractive feature leads to a possible adoption of the capillary barrier as effective measures for slope protection of natural soil or embankment. On the other hand, in the case of a horizontal interface constructed in a farm field, water retained will be effectively consumed by plant growth. This water storage above the interface of the soil layers and within the plant root zone leads to another possible adoption of the capillary barrier as a water saving irrigation in the farm fields. In the paper, possible field applications of the capillary barrier of soil are reviewed based on results of some field experiments published previously.
