Abstract

This research has been done for the study of morphology of Ghezel Ouzan River from Ostoor to Manjil dams in two GORGE and floodplain basins at 37 years period based on aerial photos, topographic maps and field surveying. The results showed the mean SINUOSITY ratios of, 1. 46 and 1. 22 for GORGEs and floodplain basins so that they can be classified as MEANDERing and sinuous river reaches respectively. More SINUOSITY at GORGE basin is due to the geological and tectonically factors. In the other words, the river plan initiate and mature based on rock canal that originated from above mentioned geological factors. At floodplain basin in Pavehrood to manjil dam with 60 km length river reach, the river showed three obvious sinuous canaliform, sinuous point bar, sinuous braided and braided and anastomising plan. At period 37 years BRAIDING extend in the boundary about 1. 2 km widths in Hezarrood area. If the rate of widening of the river in this basin presumes in uniform rate, the velocity of the river widening is about 32 meters per year that is noticeable. Bank erosion with MEANDERing form of the river in Haroonabad area through MEANDERing growth and extensions of the loops occurred up to 850 meters at the mentioned periods. Based on central angel of MEANDERs loops, 57. 72 percents of loops are extended modes, 25. 93 % very extended, 16. 05 of others are new so the river has MEANDERing hazard. Extension mode of the loop growth is the main mode with 56% frequency and based on water shear stress distribution, geometry of loops and relative radius of the loops, consequently accumulation point of the shear stress, the modes of translations, rotation, compounding and chute and neck cut off are observed. More than 75 % of canal shifting cases of the river is toward left bank so that the construction of any structures on the left bank of the river would be dangerous.
