| Zusammenfassung |
| Ports and harbors are the major vulnerable coastal structures under tsunami attack. Resilient
harbors against tsunami impacts are essential for proper, efficient and successful rescue
operations and reduction of the loss of life and property by tsunami disasters. There
are several critical coastal structures as such in the Marmara Sea. Haydarpasa and
Yenikapi ports are located in the Marmara Sea coast of Istanbul. These two ports are
selected as the sites of numerical experiments to test their resilience under tsunami
impact. Cargo, container and ro-ro handlings, and short/long distance passenger
transfers are the common services in both ports. Haydarpasa port has two breakwaters
with the length of three kilometers in total. Yenikapi port has one kilometer long
breakwater.
The accurate resilience analysis needs high resolution tsunami modeling and careful
assessment of the site. Therefore, building data with accurate coordinates of their foot prints
and elevations are obtained. The high resolution bathymetry and topography database with
less than 5m grid size is developed for modeling. The metadata of the several types of
structures and infrastructure of the ports and environs are processed. Different resistances for
the structures/buildings/infrastructures are controlled by assigning different friction
coefficients in a friction matrix. Two different tsunami conditions - high expected and
moderate expected - are selected for numerical modeling. The hybrid tsunami simulation and
visualization codes NAMI DANCE, STOC-CADMAS System are utilized to solve all
necessary tsunami parameters and obtain the spatial and temporal distributions of flow
depth, current velocity, inundation distance and maximum water level in the study
domain. Finally, the computed critical values of tsunami parameters are evaluated and
structural performance of the port components are discussed in regard to a better
resilience.
