3D Physical Modelling of Breakwaters – Lakbi Fishery Harbour & Hadbin Fish Landing Center, Oman

Associated with Lanka Hydraulic Institute, 3D physical models were constructed to analyze the stability and performance of specific breakwater sections for the Lakbi Fishery Harbour and Hadbin Fish Landing Center projects in Oman. Bathymetry and structures were built within a 30m × 40m controlled wave basin 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) — with waves generated from multiple directions. Post-test analysis focused on rock and armour unit displacements, ensuring compliance with allowable damage levels for structural integrity. Findings from these studies played a critical role in optimizing breakwater designs for enhanced durability and resilience against varying wave conditions.

• Built 3D physical models within a 30m × 40m controlled wave basin for the Lakbi Fishery Harbour and Hadbin Fish Landing Center, Oman.
• Conducted wave loading tests across six return-period and overload scenarios, with waves generated from multiple directions.
• Analyzed rock and armour unit displacements against allowable damage levels to optimize breakwater designs.
