Abstract

The study, according to the importance of tectonic – geomorphology studies, deals with the assessment and classification of active tectonic of watershed in Kurdistan province with a comparative – quantitative approach based on the parameters of drainage network. The study includes quantitative estimation of parameters associated with tectonic drainage network and the use of hierarchical cluster analysis.The research findings showed that the studied basins are classified, tectonically active, in two different clusters. Relative comparison between the clusters show that the basins located on the first cluster have more tectonic activity with more different slopes.In this regard, the second cluster basins have less tectonic activity, more homogeneous and forming faster-cluster threshold.According to the results, it seems that the situation of the first cluster basins, with the higher tectonic activity, are due to their spatial distribution and, consequently,their impressionable of different tectonic focus particularly active faults. Also, the situation of the second cluster basins is interpreted with respect to their more homogeneous spatial position corresponding to the central region of the study area and slower activity of Sanandaj – Sirjan zone.
