ANALYTICAL SOLUTIONS ON FREE SURFACE PROFILE AND VELOCITY DISTRIBUTION INSIDE HYDRAULIC JUMP BY MEANS OF SIMPLIFIED DEPTH AVERAGED FLOW MODEL THIN THWE THWE Takashi HOSODA Manoj LANGHI Daiki CHIFU A simple depth-averaged flow model is proposed considering the deformation of stream-wise velocity to reproduce the characteristics of hydraulic jump. Initially, representing the streamwise velocity distribution using a power series of nondimensional vertical coordinate, 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 analytical solutions with two and three exponential terms for water surface profiles are compared with the previous experimental data. The velocity distributions at the origin with the critical depth are also examined with the comparisons to the previous experiments to verify the model proposed in this study. http://hdl.handle.net/20.500.12678/0000007224 https://meral.edu.mm/records/7224
