Free Surface Shear Flow Over a Wavy Bed

摘要: An analytical treatment of free surface shear flow over a wavy bed regular sinusoidal form is developed from the one-dimensional energy equation. The effects curvilinearity on velocity and piezometric heads are examined in some detail. equation expanded into series dimensionless terms to obtain systematic ordering magnitudes various associated physical quantities. third-order linearized solved expressions for phase shift between amplitude ratio waves depth variations. second-order nonlinear numerically particular flow, profiles presented graphically. configurations predicted by formulations discussed detail occurrence bi-stable moderate high Froude numbers explained.
