To determine the range of unstable morphology of rivers, streams is one of the main factors in the plan. In this paper, Changes Kor River in the area between the bridge Abbas Abad and dam Dorudzan city Kamfirouz Province Fars, Was investigated.Type the range in terms of sustainability by comparing the path of the river on the satellite images of 2001 and 2014 And topographic maps of 2004 and Google Images 2014 years, Geometrical parameters and their prevalence was determined. After creating a logical connection between all variables, How effective Mulla Sadra Dam on river morphology was analyzed. At the end of the river changes in the study area was determined using satellite images and topographic maps. The results showed that the river Kor in the range of low to very sensitive and many changes at this time. On the move and redirect rivers in the maze of rivers can be said that the development and expansion of the width and length of the arc to be seen. Handling fierce rivers and streams meandering into the arterial pattern spent meandering curve is associated with amputation and development.the coefficient of bend in the river has decreased over the years And this show from becoming a river and meander to meander developed severe sinus mode.
