Free surface shear flow over wavy bed
Effects of curvlinearity on velocity and piezometric heads are examined in some detail; equation is expanded into series in dimensionless terms to obtain systematic ordering of magnitudes of various terms and associated physical quantities; third-order equation is linearized and solved to obtain expressions for phase shift between and amplitude ratio of bed waves and depth variations; second-order nonlinear equation is solved numerically for particular flow, and profiles are presented graphically; various flow configurations predicted by linearized and nonlinear formulations are discussed in some detail and occurrence of bi-stable flow of moderate and high Froude numbers is explained.
