Abstract
Damage such as landslides has been caused by natural phenomenon like a heavy rain. As appropriate countermeasures, rather than analysing the cause of the landslide, we used methods of check dam installation and maintenance mountain basin. A check dam is a small, sometimes temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity. In this study, we analysed the adequacy of check dam built to prevent further damage after landslides through GIS and examined the sediment erosion in the existing check dams for an ideal location of check dam, considering the accessibility and size. As a result of reviewing soil loss in the study watershed according to RUSLE(Revised Universal Soil Loss Equation), the basin I had about 2% soil loss reduction, the basin II showed less than 1 % soul loss reduction, and basin III showed the reducing effect of 5 % soil erosion.
