Geographical Research

Geomorphic indexes are useful tools in identification of evaluation in trace of tectonic activity (Relatively rapid or even slow). Since the drainage network morphology and behavior changes resulting from tectonic activity are very sensitive; It seems to be evidence such as crossing the fault line and changes river bed affected by the neotectonic activities in basin. Thus، for understanding and recognition the way and the amount of performance of effectiveness neotectonic activities in morphology and behavior of Qezelchesou River، Relying on field findings، have been used from morphometric parameters such as P، AF، Br، Vf، S، Hi، SL and Smf as conceptual and model techniques. The purpose of this study is understanding of evidence and evaluation neotectonic activities. For achieving this purpose، aerial photos، satellite images، topographic and geological maps as research tools have been used. The results of geomorphic indices show that Study area entirely influenced by neotectonic activities، but amount of influence is not the same in all Sub watershed، As in the northern part (anjiran) is higher. Obviously Assessment river reaction to gain access to a method for finding out the amount of channel stability can be provide based Information for studies land use planning.
