토지이용에 따른 강우-유출 특성 변화(농지조성 및 농어촌정비)

Variations of Rainfall-Runoff Characteristics with Landuse

The purpose of this study were to monitor rainfall and runoff data from paddy blocks and forest areas at the Balan Experimental Watershed, and to investigate the variations of runoff characteristics with different land use. Field data showed that the total runoff from paddies and forest areas are not significantly different in volume. The peak discharge from forest areas was less than that from paddies for lighter storms, but became greater for heavier storms. The results demonstrate that paddies play an important role to reduce peak discharge from heavy storms as compared to forest.
