Investigation the Potential of Morphological Change Urmia Shahrchi River

The purposes of this study are investigation of Shahr Chai river patterns, its stability and subsequently changes in the period of 2000-2013. For this purpose were used Landsat images, topography, geological maps and hydrological data. For study of river pattern and its changes was used Sinuosity and Meander Central Angle Indexes. Also for study of river stability was used by shear stress ýand RBS indexes. Results indicated that river pattern changes are very low. River stability analysis indicated that totalý shear stress rate is higher than critical shear stress. Results show that potential of river is high for creating of morphological changes in costal interval but decreasing of river flow has been caused that river changes be in lowest amount possible.
