Abstract
The main purpose of this study is to find the appropriate method to prevent the reduction of infiltration capacity due to sealing of soil surface. The study results indicate that installation of gravel or larger soil facilitates the drainage of infiltrated rainwater. However, considering that the infiltration capacity has been reduced since the installation, it seems that the sealing of soil surface is caused by the inflow of suspended soil into the lower sand layer. To promote the infiltration capacity by reducing the pounding of lower natural soil layer, the sand soil should be placed above the natural soil layer with shallow depth just below the larger gravel. Furthermore, the crust generated above the soil surface should be removed regularly and the sand layer above the natural soil layer should be replaced with new one so that the original infiltration capacity can be maintained properly.
