Figure B10. View of the wave guide at upstream end of the beach. The opening
beneath the wave guide is 0.15 m high along the entire length of the
wave guide. A matrix of polyvinyl chloride pipe, behind the wave
guide, directs the externally recirculated current onto the beach
Figure B11. A matrix of PVC pipe was installed immediately upstream of each
vertical turbine pump to absorb residual wave energy and to
minimize wave reflection in the flow channels. Low-crested weirs
were installed in each flow channel to help block any sand that
passes over the sediment traps, before it reaches the pumps
