Abstract: In this study, different methods of baseflow separation were used to analyze the daily runoff data measured by the hydrologic observation station in HuangBengLiu Gully, Gongga Mountain. The separation results, mean value, meanvariance and coefficient of deviation of the baseflow indices were calculated. Baseflow process and lag time of the runoff and baseflow in HuangBengLiu Gully were analyzed. The baseflow indices were found to range from 0.65 to 0.74 in HuangBengLiu Gully and averaged 0.7. In the dry season, the runoff of HuangBengLiu Gully lagged 2.7 to 14.5 days relative to the rainfall and averaged 8 days. The baseflow lagged 0.7 to 3 days relative to the runoff and averaged 1.8 days. In the wet season, the runoff of HuangBengLiu Gully lagged 0.7 to 3.7 days, with an average of 1.8 days, and the baseflow lagged 0.9 to 2.6 days, with aa average of 1.5 days. When considering basin as whole, the calculated precipitation infiltration recharge coefficient ranged from 0.16 to 0.28. The results showed that the stability and reliability of the separation results by F4 digital filtering method are the best. The runoff lag time relative to the rainfall in the wet season was shorter than in the dry season, but the differences in baseflow lag time between wet and dry season was relative minor. According this study, we argue that multiple methods should be used to separate baseflow from runoff of a watershed, and the stability and reliability of the separation results should be considered. The whole basin problems should be considered when calculating groundwater recharge with watershed, especially in the mountains.

Key words: forest system, small watershed, baseflow separation, precipitation infiltration coefficient
