STUDY OF OUT-FLOW DISCHARGE CONTROL FOR ARTIFICAL SOIL

Abstract

Since artificial soil is shallow and has drain phase, seepage of rainwater in artificial soil differs from the natural soil. Authors investigated the seepage of rainwater into the soil from the viewpoint of out-flow discharge control. The experiment was conducted for different types of vegetative soil and for different thicknesses, using rain making equipments. It has been found that at the end of the rainfall, the soil doesn't get saturation because of the factors such as differences in structures and swelling capacity of soils.
