Abstract

The environmental impact of the engineering project was taken into account when carrying out comprehensive studies of shore protection engineering measures for the Lazurnoye region of the Kherson region of Ukraine on the north-western coast of the Black Sea. The optimal configuration of hydrotechnical structures are choosen to protect the beach in the region of the incoming wave impact. The entire coastline of the Lazurnoye region is about 3000 meters. In the course of modelling and numerical experiments, the transfer of bottom sediments to the coast, the evolution of the coastline and beaches, and other coastal processes were studied. The project of comprehensive coastal protection of the Lazurnoye region, presented on the basis of mathematical and hydraulic modelling, has allowed the development of engineering solutions that meet coastal protection and environmental requirements. The most expedient variant of coastal protective measures was the creation of a system of the beachprotected structures capes from sections of the permeable slope-steps designs with wave damping chambers. The presented research results and the solution of many problems of the dynamics of the coastal zone of the sea can be considered as an attempt to manage coastal processes on rather large and complex sections of the coast with a joint solution to the problems of hydraulic engineering, management of water quality in the coastal zone of the sea, and the choice of optimal options with the least impact on the environment.
