英文摘要	Baseflow is the slowly varying portion of streamflow, and it is essential for sustaining river flows. Several methods have been developed for separating baseflow from streamflow. However, due to the lack of measured baseflow, past studies generally compared these baseflow separation methods qualitatively based on their hydrologic plausibility. To quantitively determine which baseflow separation method has the best accuracy, this study established a reliable evaluation criterion that relies only on measured streamflow. By applying the evaluation criterion to 1815 catchments across the contiguous United States, 9 baseflow separation methods including 4 graphic methods and 5 digital filter methods were evaluated. The evaluation result shows that the digital filter method proposed by Eckhardt (2005) has the best performance, and its performance is independent of catchment characteristics. Thus, Eckhardt digital filter method is recommended for baseflow separation across the contiguous United States.
