3D Physical Modelling for Breakwater Design - Lakbi Fishery Harbour, Oman

Associated with Lanka Hydraulic Institute, a 3D physical model was constructed to analyze the stability and performance of a specific section of the designed breakwater. The bathymetry and model was built at a 1:63.23 scale within a controlled basin environment to simulate real-world wave conditions.

Comprehensive wave loading tests were conducted for multiple return periods: 1-Year, 5-Year, 10-Year, 50-Year, 100-Year, and an Overload Condition (High Water Level and Low Water Level). Waves were generated through two directions, 90E and 145SE. Post-test analysis focused on rock displacements, ensuring compliance with allowable damage levels for structural integrity. The findings from this study played a critical role in optimizing the breakwater design for enhanced durability and resilience against varying wave conditions.

• Built a 1:63.23 scale 3D basin model to test breakwater stability and performance.
• Conducted wave loading tests for 1, 5, 10, 50, and 100-year return periods plus an overload condition, from two wave directions (90E and 145SE).
• Analyzed rock displacements against allowable damage levels to optimize the breakwater design.
