Description 443-448
Laboratory investigation on perforated hollow piles in a single row was
conducted in a two dimensional regular wave flume to study the performance of
such an arrangement in dissipating wave energy. The influence of spacing between
the piles, size of perforations, different percentage of perforations and water
depth on wave attenuation has been investigated. It is found that water depth
has insignificant effect on transmission coefficient (Kt) at
higher wave steepness. Kt decreases as the relative
clear spacing of piles (b/D) decreases and also it decreases as the
incident wave steepness increases. At lower value of b/D, Kt
decreases with increase in percentage of perforations. For the same
percentage of perforations, the pile groups with larger size of perforations
transmit more wave energy than pile groups with smaller size of perforations.
The perforated hollow pile breakwater is an alternative solution to protect the
coast from erosion where the erosion is due to wave energy concentration or
onshore offshore movement of sand.
