Abstract
The centrifugal force generated by open channel flow around curves will push the water particles away from main stream to radial direction. In order to maintain water particle equilibrium at the bend section, a differential rise in water surface beside the outside wall and a depression along the inside wall is created. This water surface rise causes a pressure force xP to balance the flow against the centrifugal force.The rise of water surface above the mean water level is called Superelevation. Due to steep terrain natures, land acquisition, innovative flood mitigation designs in urban areas,inaccurate cited equations for estimation of superelevation at bends.Accordingly it is essential to investigate 3D flow field around bends, establish design charts for superelevation at supercritical flow (Fr = 1.3 {u2013} 2) with sharp bends wherer/b<3, to determine the bend outer walls height, and study the extended bend protection against high shear stresses for these sharp bendsdies, and identify the locations of maximum superelevation along the bend radial section
