Resumen
The calculation of base flow rates in rivers is complex since hydrogeological and hydrological
studies should be performed. The estimation of base flow rates in storm hydrograph associated to
various return periods is even more challenging compared to other events. This research provides a
novel methodology to compute base flow rates in gaged rivers for extreme events based on statistical
correlations of daily flows. The current methodology does not require complex aquifers analysis to
compute base flows. Results of computed base flow rates are validated using observed storm hydrographs using a complete record. The proposed methodology was applied considering measurements
of a limnigraphic station in the Sinú river located in Montería, Córdoba, Colombia. The analysis
confirmed that only using series of multiannual monthly mean flows is possible to estimate base flow
of flood hydrograph associated to different return periods.
