Streamflow information is the integrated response of the river basin, such as topography, soil and vegetation to external impacts such as climate. A regionalization of annual data is carried out using k-means analysis. Streamflow series from 80 gauging stations were chosen to characterize geographic differences in year to year streamflow variability. The eight-cluster solutions of k-means analysis are stable and interpretable with reference to spatial and temporal variations. It was shown that western Turkey is dominated by a relatively large cluster, indicating strong influences of the Mediterranean dynamics. The resultant map was given at the 8-cluster level, showing the spatial variability of homogeneous streamflow regions.born digitalproceedings (reports)engCopyright and other restrictions may apply.
