DEVELOPMENT OF A METHOD FOR DETERMINATION OF LOCATION OF MAXIMUM SHEAR STRESS IN RIVER BENDS (VERIFICATION OF REPORT NO. 592, IRANIAN ENERGY MINISTRY

Hydraulic conditions and identification of reach based on which maximum shear stress occurs are very complex problems in river bends. In this research, a method is developed for determining the location of this reach in bends. In addition, results of this method are compared to instructions of report No. 592 (prepared by Iranian Ministry of Energy). Downstream of the Karkheh dam is the case study of this research. The reason for selecting this region is evaluation of effects of dam construction on river bends.The number of bends was 24 in 1996 (before construction of dam) and was 42 in 2011 (after construction of dam). Important results of this research are: 1-For $R/W
