Summary
A beach nourishment study was carried out at Mount Maunganui Ocean Beach, adjacent to the Entrance Channel into Tauranga Harbour. An aspect of the study was to predict the movement of nourishment material from a dump mound in the nearshore (4-7 m water depth). The prediction methods used included: a UV fluorescent sand tracing experiment and 2 prediction methods developed by Kraus et al. (1991) and Hands and Allison (1991). The results show that the dump mound would be actively eroded, and would move in a shorewards direction under prevailing wave conditions.
