In this study, to investigate the disturbance drainage basin, 80 sub-basins were determined. The maps of geology, drainage, raster maps, fault basin was prepared. The performance area and perimeter of the basin, number and length of channels, frequency of drain, angle General, Internal angle faulting density, and angle of internal and public were calculated. The number of faults in the fault zone is about 10 to 15. These fault zone rock properties of marl, limestone, flysch, limestone, dolomite and limestone were Cenomanian. Analysis of variance based on lithology and density fault factors showed that there was a significant difference between the studied variables. Results of mean comparison with Duncan test showed that the sub-basins located on fault zones 2 and 3 are most disturbed drainage, respectively. Multivariate analysis results indicated that sub without fault in a category. Sub-basins of 73, 50, 51 and 72, however, the role of the effects of no-fault. But according to studies done on morphometric characteristics of a fault in the sub-groups, respectively. Sub basin of 2, 13, 4, 6, 14, 16, 23, 8, 39, 34, 70, 77, 80, 52, 67, 78, 7, 12 and 79 were the only sub basin that is likely to have undiscovered fault, was high.
