Preliminary Study on Baseflow Separation at Watersheds in East Java Regions

This research aims to determine the range of parameter value, baseflow index and the appropriate method for base flow separation. Seven (7) recursive-digital-filters (RDF) and two (2) graphical methods are used for this study. Discharge data from 8 watersheds in the administrative area of UPT PSDA Bondowoso in East Java were used to test the methods. Firstly, each method was calibrated using…
