Abstract: In urban drainage networks, manhole structures are used to dissipate energy and to decrease flow velocity, especially in steep slope areas. The purpose of this study is the numerical and experimental modeling of a new drop ...

Abstract: A large variety of hydraulic jumps on horizontal and sloping inverts at the end of an ogee standard weir is investigated. An ogee standard weir was used to create supercritical flow and slopes of 0.0,

Abstract: An analytical model for evaluation of boundary shear stress in compound open-channel bends is developed. Perpendicular volumetric elements are generated in all cross sections of a bend. Each element represents an equation ...

Abstract: The energy loss of the vertical drop with subcritical flow in the upstream channel has been studied experimentally with a physical model of

Abstract: Semianalytical equations were derived to evaluate the mean boundary shear stress in smooth trapezoidal open channels using conformal mapping techniques. This process tends to a complicated function that should be simplified ...
