Abstract

This study concentrates on the changes of theoretical wave power from offshore to coastal regions of south-western Black Sea. The investigation also offers a long-term (31-year) wave power quantification analysis between 1979 and 2009 using the SWAN version 41.01AB numerical wave model. The wave resource assessment is performed in terms of its seasonal and monthly variability of wave power, annual wave power directional distributions and the comparison of the maximum and median values of some important wave power parameters in the west of Istanbul a major city in Turkey that straddles Europe and Asia across the Bosphorus Strait. For this analysis, 10 point locations distributed on two perpendicular lines (KA and KE) to the coastline with five different depths (5, 25, 50, 75, and 100 m) in the areas of interest were selected. The data needed was extracted from the dataset produced by [1, 2] using a calibrated nested layered wave hindcast model SWAN forced with CFSR winds. The results show that the wave energy resource in the study area is high, and the potential locations can be considered for extracting wave electrical power.

Highlights

  • By the time energy demand is increasing very fast on the earth, if we do not find various clean energy resource options, fossil energy will cause lots of negative impacts on the environment

  • If we look back to twenty years ago, the wind energy was in the same place as ocean wave energy is today

  • In order to enhance the light on convertible wave power in the south-western coasts of the Black Sea, a 31 year (1979-2009) wave power resource assessment was presented in this research work

Summary

Introduction

By the time energy demand is increasing very fast on the earth, if we do not find various clean energy resource options, fossil energy will cause lots of negative impacts on the environment. One of these impacts is the greenhouse gasses, which is a fatal warning for lives on the earth. There are many prototype wave energy farms working nowadays, but they are not commercial yet Another essential aspect for extracting wave power is to investigate the interested geographical locations to have some ideas about the status of waves and the wave power, the continuity, or the variability of wave power distribution in time. The characteristics mentioned above are investigated in five different depths from very deep water to very shallow water (shoreline)
