摘要：
Slope-related disasters have been happened between July and September which is rainy reason in Korea. It is known that the rainfall is one of the most important that lead to slope-related disasters. Based on slope analysis, rainfall intensity was applied as a factor of rainfall. It was calculated groundwater level in case of 100% rainfall infiltration. This paper calculated the amount of infiltration by using slope inclination, soil type and executed comparative analysis. NRCS model has the highest suitability level among analytic infiltration models. As a result, soil type occurred greatly permeation by the biggest permeability coefficient, and the small amount of infiltration in hydraulic conductivity happened in occasion of small D soil type. Also, this paper concludes the increasing in the amount of infiltration as slope and soil condition to calculate according to soil condition of slope range from D type to A type, and that infiltration occurs little and the slope is steep.
