ENVIRONMENTAL EFFECTS OF T-SHAPED GROINS BUILT ON THE EASTERN BLACK SEA COAST ON SHORE PROTECTION

摘要

The construction of the double highway on the Black Sea Coast was initiated in 1998, completed in 2000. During the construction, T-shaped groins where were built to protect the shore. In this article, the contribution of T-shaped groins to beach formation and their positive or negative effects on the change of coast and submarine topography were environmentally examined.For this purpose, before the research on the map the groins were marked then the places where the groins would be constructed were levelled by taking soundings and their bathymetric maps were prepared. After the groins were built, the surrounds of the T-groins were determined by taking data with the echo sounders device and their bathymetric maps were prepared again.Afterwards, these are whose construction was completed were observed at the beginning of winter, at the end of winter, at the beginning of summer, and at the end of summer. These observations investigated whether a beach was formed on the coast and the environmental effects conclusions were investigated. At the end of the study, the effects of the groins on submarine topography in terms of shore protection and the positive or negative environmental contributions to the shore were determined and the data were shown in graphs and figures.
