Figure B12. Two 400-mm-diam polyvinyl chloride pipes were installed in the
concrete beach, to passively recirculate the longshore current that
flows in the swash zone. The two "swash zone traps" (i.e., sand trap
No. -1, and -2) can be seen in the bottom right corner of the figure
Figure B13. An overall view of the facility after the sand beach has been graded
to have straight and parallel depth contours. The sediment traps can
been seen near the bottom, with the adjustable boundary along the
interface between the sand beach and the sediment traps. Once the
tractor is driven out of the facility, the gate is closed and the facility
is filled with water to begin an experiment
