ONE-DIMENSIONAL EQUATIONS OF OPEN-CHANNEL FLOW

ONE-DIMENSIONAL EQUATIONS OF CONTINUITY, MOMENTUM, AND ENERGY FOR UNSTEADY, SPATIALLY VARIED FLOW IN A FIXED-BED OPEN CHANNEL OF ARBITRARY CONFIGURATION ARE DERIVED FROM THE POINT FORMS OF THE CORRESPONDING DYDRODYNAMIC EQUATIONS BY INTEGRATING THE LATTER OVER A DEFORMING REGION OF SPACE COMPRISING A SLICE OF DIFFERENTIAL THICKNESS ACROSS THE FLOW WITH A TOP ALWAYS COINCIDENT WITH THE FLUCTUATING WATER SURFACE. TO BRING THE EQUATIONS TO THE FORM OF SAINT VENANT IN FIXED AND ACCELERATING REFERENCE FRAMES, DEPARTURES FROM HYDROSTATIC PRESSURE CONDITIONS IN A CROSS SECTION DUE TO LATERAL ACCELERATION, VISCOUS DEFORMATION, AND TURBULENT REYNOLDS STRESSES ARE REPRODUCED EXACTLY, THE RATE OF ENERGY DISSIPATION IN A CROSS SECTION IS UNIQUELY RELATED TO WALL SHEAR OVER THE WETTED PERIMETER & THE TERM ACCOUNTING FOR LATERAL DISCHARGE DEPENDS UPON ITS NATURE. BULK OUTFLOW IS CONSIDERED. /ASCE/
