The hydrological model calibration is a challenging task, especially in ungauged
catchments. The regionalization calibration methods can be used to estimate the parameters …

Cluster analysis methods are one of the most widely-used types of methods in
regionalization of watersheds for regional flood frequency analysis. Several cluster analysis …

Identification of groups of watersheds with similar flood generation mechanisms and the
same hydrological responses is an important step of regional flood frequency analysis which …

In this study, an algorithm inspired by some concepts of the rough set theory is proposed for
regionalization of watersheds. The algorithm includes a clustering step and a classification …

Identification of hydrologic homogeneous regions (HHR) facilitates prioritization of
watershed management measures. In this study, a new methodology involving a …

The method used for feature selection or feature weighting in regionalization of watersheds
may affect the results of regionalization methods considerably. It can play a key role in …

The performance of regionalization methods used for regional flood frequency analysis is
affected considerably by the features used to identify the homogeneous regions (eg …

Regional flood frequency analysis (RFFA) is a widely recognized technique for estimating
reliable flood quantiles at ungauged sites or to augment the data available at gauged sites …

Regional frequency analysis (RFA) serves as a useful tool for flood estimation at a regional
level, to improve the precision of estimated flood quantiles or for prediction in ungauged …

Use of flood statistics in the regionalization of watersheds may improve the homogeneity of
regions. However, it is not possible to use the feature vectors, including the flood statistics, to …
