ABSTRACT

This study conducted a rainfall infiltration test for weathered soils of different parent rocks in order to investigate infiltration characteristics. The changing pattern of pore water pressure was identified and compared with the numerical analysis results to analyze ground infiltration characteristics in relation to rainfall characteristics. The results of rainfall infiltration test and numerical analysis showed that the infiltration capacity became higher when the infiltration coefficient of weathered soil was large given that the same rainfall intensity was applied. Additionally, it was found that the movement of wetting front was fast in accordance with the changing rainfall intensity. The analysis results indicated that ground infiltration coefficient, rainfall intensity and duration were the major factors influencing ground infiltration process.
