MODEL STUDY OF SUPERCRITICAL FLOW CHANNEL TRANSITION FOR NICHOLS CREEK, KENNEDY, TEX.

A GEOMETRICAL UNDISTURBED MODE., ONE TWENTY-FIFTH OF THE PROTYPE, WAS USED TO STUDY THE TRANSITION AND ITS ENTRANCE. THE INSTALLATION OF THE MODEL IN A FACILITY THAT INCLUDED PORTIONS OF THE APPROACH AND EXIT CHANNELS IS ILLUSTRATED. THE DESIGN DISCHARGE RATE OF 3.950 C.F.S. WAS INTENSIVELY INVESTIGATED, BUT DISCHARGE RATES OF 1,500 AND 2,750 C.F.S. WERE ALSO STUDIED FOR THEIR POTENTIAL FOR CREATING EXCESSIVE WAVE HEIGHTS. AN ADDITIONAL DISCHARGE RATE GREATER THAN THE DESIGN RATE, 4.600 C.F.S. WAS ALSO INVESTIGATED. TEST RESULTS ARE DETAILED. AMONG THE ASPECTS DISCUSSED ARE THE PERFORMANCE OF THE ORIGINAL DESIGN, THE EFFECT OF CHANGING THE MATERIALS ON THE SIDES OF THE ENTRANCE, THE EFFECT OF REMOVING FLAT CRAST FROM THE ENTRANCE, REVISED SINGLE-CURVE TRANSITIONS AND THE EFFECT OF ENTRANCE ALTERATIONS. NEW PARABOLIC TRANSITION AND THE EFFECT OF ENTRANCE ALTERATIONS ARE ALSO DISCUSSED. BASED ON THE STUDY, RECOMMENDATIONS ARE FORMULATED AND CONCLUSIONS ARE PRESENTED.
