【 摘 要 】

The present study deals with the supercritical flow characteristics and the effort has been made to verify analytical and empirical relations based on extensive experimentation for different characteristics namely: sequent depth ratio (h2/h1), efficiency of jump (E2/E1), relative height of jump (hj/E1) and relative length of jump (Lj/h2). Also, the existing models for different channel conditions are discussed; significance of Froude number and Reynolds number for a range of velocity mentioned in literatures are highlighted; models proposed by different authors and its validation were also explained. Undular jump formation and the role of turbulent boundary layer were also explained for Froude number varying between 1.3-2.3. All the characteristics are found suitable with existing relations and can be used as guidelines for the analysis of different channel and channel conditions.
