	%X Scouring around a bridge pier is a complex
phenomenon. More laboratory experiments are required to
understand the scour mechanism. This paper focused on time
development of local scour around piers and piles in semi integral
bridges. Laboratory data collected at Hydraulics Laboratory,
University of Malaya was analyzed for this purpose. Tests were
performed with two different uniform sediment sizes and five ranges
of flow velocities. Fine and coarse sediments were tested in the
flume. Results showed that scour depths for both pier and piles
increased with time up to certain levels and after that they became
almost constant. It had been found that scour depths increased when
discharges increased. Coarser sediment also produced lesser scouring
at the piers and combined piles.
