The energy and momentum correction coefficients at the maximum flow constriction were found to be related to the inverse of the upstream-to-downstream discharge ratio of the main channel. The cross-sectional mean flow angle at the branch channel entrance was determined through detailed measurement of velocity vectors and was found to decrease as the discharge ratio increases. The shape index of the separation zone was also checked through observations of surface-dye trajectory and was found to agree with that obtained in pre
