The existing rock mound technology specifically those erected for rock oyster (saccustrea cucullata) posed several problems such as growth efficiency, water circulation, sediment accumulation and durability against waves. This paper investigated in a laboratory scale using a physical model of a coastal zone. About 141 test runs were made to measure and observe resilience, wave breaking ability, sediment transport and water circulation of five different rock mound shape and set-ups/arrangement. Data showed that the droplet and the diamond shape arranged in staggered formation was the optimum design. The droplet shape provided the more cost-effective design as a rock oyster mound and as a breakwater set-up. Validation of the design in an actual environment is recommended.
