REDUCTION OF SCOUR AROUND BRIDGE PIERS, PART II

THE INTERIM REPORT PRESENTS LABORATORY SCOUR REDUCTION INFORMATION ON THE EFFECT OF CLUSTERS OF CIRCULAR PILES PLACED UPSTREAM OF SKEWED BRIDGE PIERS. APPROACH ANGLES OF 10, 20, AND 30 DEGREES, ARE INVESTIGATED ON CIRCULAR, ROUND- NOSED, AND RECTANGULAR TYPE PIERS. PILE CLUSTERS CONSIST OF FROM THREE TO SIX PILES ARRANGED EMPIRICALLY FOR EACH FLOW APPROACH ANGLE AND PIER TYPE TO PROVIDE THE GREATEST SCOUR PROTECTION. THIS REPORT SUPPLEMENTS PART I WHICH CONTAINS SIMILAR INFORMATION FOR FLOW PARALLEL TO THE PIER. SINGLE SKEWED PIERS ARE TESTED IN A TWO FOOT WIDE FLUME AND TWIN SKEWED PIERS, ONE PROTECTED AND ONE UNPROTECTED, ARE STUDIED IN A SIX FOOT FLUME FOR PURPOSES OF COMPARISON. /BPR/
