- FIELD OBSERVATION AND NUMERICAL SIMULATION FOR SEDIMENT RUNOFF DUE TO LAND DEVELOPMENT IN NGERIKIIL WATERSHED, REPUBLIC OF PALAU
抄録
Soil erosion and runoff have led to environmental problems in Babeldaob Island, Republic of Palau, and effective measures which can reduce sediment yield in the developing bare land are necessary. This paper aims to quantify the sediment runoff from land development zone in Ngerikiil watershed at southern part of Babeldaob Island. The following three points were clarified. First, field observed results showed that severe soil erosion at the land development zone affects the behavior of sediment movement in the watershed. Second, 556 t/ha/y of soil erosion at the developing bare land was estimated by using observed data. Third, the Water Erosion Prediction Project (WEPP) model was tested to verify their applicability in predicting sediment yield at a land development zone. The sediment yield which was calculated under various landform and landuse conditions was reasonable.
