UNIFIED NONDIMENSIONAL FORMULATION FOR OPEN CHANNEL FLOW

THE SPECIFIC FORCE, SPECIFIC ENERGY, AND A CHEZY-RESISTANCE SOLUTION FOR GRADUALLY VARIED FLOW IN WIDE OPEN CHANNELS ARE PRESENTED ON A SINGLE NONDIMENSIONAL DIAGRAM WITH A COMMON DEPTH ORDINATE. THE GRADUALLY VARIED FLOW SOLUTION APPEARS AS IOPLETHS OF LENGTH ALONG THE CHANNEL, FROM A SPECIFIED INITIAL DEPTH, ON AXES OF NORMAL DEPTH AND FLOW DEPTH. LINES ON THE DIAGRAM REPRESENTING NORMAL DEPTH, CRITICAL DEPTH, AND TRANSITIONAL DEPTH PRODUCE A NATURAL DIVISION OF WATER SURFACE PROFILES INTO M, S, C, AND H CATEGORIES. THE UNIFIED APPROACH REPRESENTED BY THIS GENERAL OPEN CHANNEL DIAGRAM SHOULD PROVE USEFUL IN THE UNDERSTANDING AND PRELIMINARY ESTIMATION OF BOTH RAPIDLY AND GRADUALLY VARIED STEADY FLOWS IN OPEN CHANNELS.
