Description | ||||||
A simple depth-averaged flow model is derived considering the deformation of stream-wise velocity to reproduce the characteristics of hydraulic jump. Initially, representing the stream-wise velocity distribution using a power series of dimensionless depth, the dependency of coefficients in the power series on the spatial coordinate is formulated using 2- D continuity and momentum equations. The water surface profile equation for a hydraulic jump is deduced using the depth-averaged continuity and momentum equation with iteration procedures. Then the calculated approximate solutions for water surface profiles are verified with the previous experimental data. | ||||||
