The purpose of this research is to quantitatively investigate the characteristics and pattern of the bends of the studied path of Qezel Ozen river, so that the characteristics and specifications of the bends of the study area can be determined. To achieve this goal, considering the dimensions and extent of the study area From satellite images and the possibility of processing information using the geographic information system, it was necessary and necessary. Therefore, ETM+ satellite images from 2000 and 2004 and IRS for 2007 were used. The results showed that during the three studied periods, the river changes in the studied periods are completely different. So that the amount of changes in the first period during the three periods was very high and the second period had the least amount of changes in the three periods. The values of the central angle and curvature coefficient show that in all the investigated intervals, changes in the curvature coefficient and central angle (except for a small proportion in mountainous areas) are observed in a limited range, which indicates the existence of almost similar arcs along the route. It is a river and it is also developed based on the central angle index of the meandering pattern of the river.
