Abstract

The active fault of North Sarbisheh from the main branches of the Nehbandan fault zone, in the middle part of the Sistan suture zone has two trends, northwest-southeast and east-west .Due to the fact that the North Sarbisheh fault consists of different segmentation, the fractal dimensions of the streams were calculated in four parts of Bijaem, Baghestan, Rumashk and Dastghich. The average fractal dimensions of the streams in order to compare the tectonic dynamics in this fault zone, in the Baghestan segment, is 1.98 compared to the parts of the Dastghich, Rumashk and Bijaem at 1.96 due to the linearity of the waterways and the density of the lower surface congestion in these three parts, indicating Most of these tectonic activities are related to Baghestan fault zone. Comparing the fractal dimensions of the waterways and, accordingly, the direction of the fault in different parts and the evidence obtained, shows that the deformation progress of the present era is towards the eastern part of the fault.
