Flow duration curve regionalization with enhanced selection of donor basins
A non-parametric regionalization procedure for the assessment of flow duration curve (FDC) at ungauged basins is presented. This modeling approach is fundamentally based on the quantification of dissimilarity between FDCs, thus allowing the grouping of most similar basins. An analogous grouping procedure, performed in the space of selected basin characteristics, allows the estimation of FDCs also at ungauged sites; however, for a fixed set of basin characteristics, some ungauged basins cannot be properly represented due to the scarcity of close (similar) donor basins. For these cases, the proposed method allows for the selection of an alternative set of basin characteristics as a support for similarity grouping. The results of the study show that the statistical error can be significantly reduced by following the proposed methodology. About 10% of all the basins involved in the analysis can benefit from the model swapping procedure, thus improving the final predicted curve.
