      Laboratory flume experiments to investigate the characteristics of scour around bridge pier by live-bed scour condition are performed. This study examines the comparison of maximum scour depth on clear-water condition and live-bed condition at the circular shape of bridge pier.
      The experiments were conducted in a 0.9m-wide, 0.45m-deep flume with 8m-length in a straight channel. An approximately 15cm layer of sand with a median diameter of 0.2mm formed the bed. Both the water and the sediment transported were recirculated throughout the flume and return curcuit by a centrifugal pump. For the sake of live-bed condition, sediment supply apparatus utilized.
      The results show that clear-water condition is larger maximum scour depth than live-bed condition. The aspect of scour depth also appeared that clear-water condition is longer time of scour depth because bed material grain is big and velocity is slow.
