- Abstract
Coral Reefs in the Bali Sea are complex structures that prevent beaches from erosion, serve as habitat for sea life and are a major resource for the local fishing industry and tourism. Currently, however, they are threatened and partly already destroyed by dynamite fishing, ocean acidification due to elevated levels of CO2, in turn caused by pollution, and rising sea temperatures due to global warming. Semi-artificial reef systems could help to repair damaged structures and initiate new reefs. This research investigates if geometrical complexity in artificial coral reefs based on Biorock® Technology has an impact on its function as a reef. We propose novel design, fabrication and assembly methods for artificial reefs. Two artificial pilot reefs, Prototype 1 and 2, were successfully launched and monitored for six years and one year, respectively, in Gili Trawangan, Indonesia. We investigated in detail the growth and structural performance of the developed prototype in the sea. We used underwater photogrammetry, a method to three-dimensionally reconstruct high resolution underwater photographs of PT#1 and a natural reef to build detailed 3-D models of both. This procedure enabled us to visualize, structurally analyse, and to compare geometrical performance of a natural reef with the proposed artificial solution. We also constructed turbulence models based on computational fluid dynamics simulations. Our results demonstrate that geometrical complexity has an impact on the artificial coral reefs' functional and structural performance in the sea.
