dc.description.abstractTechnique baseflow separation can be performed by methods Recursive Digital Filter (RDF). This research dealt with estimation of baseflow contribution at seven watersheds in the administratif area of UPT PSDA Lumajang. Six methods filter were used to separated baseflow from total flow. Methodology consist of : (1) data inventorying (2) data processing, (3) calibrating and validating, and (4) models performances evaluating. Daily discharge were used as main input for the analysis 1996-2005. Furthermore, each algorithm was calibrate using daily discharge data for each year. The mean values of parameters obtained were then used to separate baseflow for whole periode of record. RMSE, scatter plot and FDC were used to evaluate the model performance during dry periode (Juli to September) assuming that for this period no rainfall have occurred. Calibration was conducted on each the watershed with the same way. Validation was conducted from the watershed complete data (Rawatamtu watershed). The results showed that filter method, Lynie-Hollick perform better then others algorithmsen_US
