토양유실 저감을 위한 지표피복 저감효과 변수 결정 및 SWAT 모형 유역단위 효과 분석 = Determination of Model Parameters of Surface Cover Materials in Evaluation of Sediment Reduction and Its Effects at Watershed Scale using SWAT

다국어 초록 (Multilingual Abstract)

The purpose of this study was to determine parameters of surface cover materials and evaluation the effects on runoff and sediment reductions with rice straw mat with PAM at watershed scale using the SWAT model. In this study, 1) regression equation of CN for rice straw mat ＋PAM using SCS curve number method was developed, 2) the USLE P factor, being able to reflect simulation of rice straw mat＋PAM in the agricultural field, was estimated for various slope scenarios with VFSMOD-w. Then regression equation for CN and USLE P factor were used as input data in the SWAT model. Assuming rice straw mat＋PAM is applied to radish and potato fields, occupying 24% of agricultural fields at the study watershed. Result of direct runoff without rice straw mat＋PAM was 65,964,368 m3, with rice straw mat＋PAM, direct runoff was 65,637,336 m3 327,031.8 m3 reductions compared without it. Also, result of sediment without rice straw mat＋PAM was 163,531 ton, with rice straw mat＋PAM, sediment was 84,779 ton, 78,752 ton reduction compared without it. This analysis showed that about 48% sediment reductions would be expected with rice straw mat＋PAM. As shown in this study, rice straw mat＋PAM would be used as an efficient site-specific BMPs to reduce runoff and sediment discharge from field.
