Abstract
This study was carried out to evaluate precipitation, geological and topographical factors from the landslide area occurred in Maeri, Sangdong-myeon, Gimhaesi, Gyeongsangnam-do. The landslide was affected by geo-topographical factors. Talus which is infiltrated easily by runoff was widely distributed in the landslide area. Concave areas on back- and toe-slope were built up colluvial materials and weathered soils. The colluvial materials were consisted of less weathered pebbles and stones (diameter: 10~100 cm) which are easily infiltrated during rainfall events. Also the landslide was mainly affected by an ascending of ground water table which is low in summit and high in toe-slope due to geo-topographical characteristics of the landslide area. The most important reason of the landslide was a lacking of drainage system of ground water despite the high infiltration rates of ground water in talus area during rainfall events.
