In this Thesis, a conceptual solution is proposed for the protection of the coastal part of the settlement of Volosko from storm surges, as well as from the combined flooding caused by high sea level and waves. In the introductory part of the paper, an overview of the Water Risk Management Plan is provided, with the main results on coastal flood hazards and risks for the area in question. In addition, this Thesis presents the results of the analysis of the probability of occurrence of high sea levels and waves off Volosko from the latest studies and research on coastal flooding and vulnerability of the coastal area. An overview of the characteristics of the Volosko and the problems encountered during storm surges and strong south wind sirocco is presented. Four possible solutions are proposed to protect the Volosko coastal zone from storm surges and overtopping waves: a low breakwater, a high breakwater, a submerged sill, and a submerged breakwater. The central part of the paper provided an overview of the analytical expressions for wave overtopping, which were then used to evaluate the effectiveness of the proposed protective structures. To evaluate more reliably the effectiveness of the proposed solutions, additional experimental investigations were carried out in the hydrotechnical laboratory. As part of these investigations, several physical models were built at a model scale. After evaluating the effectiveness, two coastal structures, a high rubble- mound breakwater and a submerged breakwater, were selected, and a stability check was performed, followed by a design of their structural elements.
