Hydrologic Regionalization of Watersheds in Turkey

Abstract

Hydrologic regionalization can be employed for importing data from gauged sites to ungauged sites. A number of techniques have been developed for hydrologic regionalization. This study presents an approach that combines three regionalization techniques in order to obtain homogeneous regions and compute streamflow at desired ungauged sites. First, an agglomerative hierarchical clustering algorithm is used to determine the number of homogeneous regions. Second, homogeneous regions are defined by the
