Abstract
Black Sea is one of the biggest inland seas in the world covering an area of 461.000 km² where six countries share a common coastline. Turkish portion of the Black Sea coastline has a length of 1650 km along with 15 cities where 9 million people live. The region is the main fishery resource of Turkey while hosting country’s major ports, industrial facilities, specific regional agricultural products (tea, tobacco and nuts), offshore oil and gas production barges and a number of planned nuclear power plants. The coastline was prone to several big earthquakes, but went through three major tsunami events (Amasya 1598; Fatsa 1939; and Amasra 1968) in the past. Therefore the upcoming tsunami event in the future will be a major threat to the people of the region as well as economy of the country. In this study, a mixed discontinuous/continuous Galerkin finite element method is applied to solve the shallow water equations describing the long wave dynamics and representing a potential hazard modelling in the Black Sea. Discontinuous piecewise linear functions for velocity and continuous piecewise quadratic functions for sea level will be both utilized while the splitting method will be used with respect to time. Grid generator for Galerkin finite element method is based on unstructured triangular cells of variable size. The results of the simulation of the Black Sea level dynamics after initial shock suggest rather narrow alert/response time window of opportunity for the coastline of Turkey.
