Resilient ports and harbors against tsunamis are essential for proper, efficient and successful rescue operations to reduce the loss of life and property by earthquake, tsunami and marine related disasters. Haydarpasa Port is located at the southern entrance of Bosphorus strait in the sea of Marmara. It is selected as case study area since it has critical components such as the main transportation hub at Asian side of megacity Istanbul, cargo and container stock areas, ro-ro handling operations and passenger terminals.  

For an accurate resilience analysis of a port, high resolution modeling, the high performance computing technology becomes essential. In this study NAMIDANCE code (2-Dimensional, depth averaged shallow water model with dispersion hybrid model) and STOC-CADMAS System (Quasi 3-Dimensional in large domains and 3-Dimensional in small domains hybrid model) are used in nested domain structures. 

For comparison of the results of both models a regular shaped nested domain structure is used.  In the case study, high resolution bathymetry and topology data for Haydarpasa region are obtained and processed to simulate selected tsunami conditions and compute/visualize all necessary tsunami parameters inside the harbor area using both models. Computed tsunami parameters in the study domains and inside the port area are compared to understand the performance of 2D and 3D numerical models and also HPC systems.
