초록

Development and application of nonpoint pollutant source model need pertinent runoff simulation for expecting good simulation result of yield of nonpont pollutant and it's move. this study purpose was compare to runoff height among Observed of Regression, HSPF and SWAT in hukchun basis loacated Gyeonggi province yangpeong-gun in two years($1998{\sim}1999$). Result, runoff height were Regression, SWAT, HSPF is 2578.96, 2526.44, 2547.21mm respectively, Nash-Schutcliff' simulation efficiency, compare to observed, was 70.22, 73.71% respectively so two simulation run off height was pertinent. If Regression method use excess observed arrange, it include error. so it's importance using pertinent arrange of observed runoff height.
