영문초록 : The purpose of this study is to estimate leachate generation volume by comparing Lab - Lysimeter with HELP Model and Other Methods, to indent& the applicability of HELP Model in domestic landfills, and to determine factors which effect leachate generation volume using regression equation. and then the results could be obtained as following ; 1. The correlation coefficients using regression equation among leachate generation volume, runoff and evapotranspiration are 0.843 - 0.967. and then of these factors, leachate generation volume is largely effected by precipitation, it will be somewhat effected by other factors, too. 2. The Coefficients of Determination( r^(2)) are 0.711 - 0.935, and 71.1% - 93.5% of Y variation in Y = a + bX can explain but 6.5% - 28.9% can't using regression equation. 3. According to simulated results, leachate generation volume is larger than runoff from January to the half of May, smaller from the half of May to September, and similar from October to December. Because rainfall intensity is larger than infiltration capacity. 4. Leachate generation volume is occasionally larger than daily inlet volume in Lab - Lysimeter as it effected by moisture which is generated during refuse decomposition,. 5. As the results of average daily leachate generation volume between Lab - Lysimeter and Other Methods, relative errors are in the range of 3.18% - 97.7% ,but relative error is very small as 0.37% in comparing Lab - Lysimeter with simulated result. 6. The large reasons in error are effected by precipitation, runoff coefficient, and compaction. Above, if HELP Model carry out field test precisely, good results can be obtained when leachate generation volume is estimated in domestic landfills.
