Characteristics of supercritical flow in rectangular channel

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;...
