TL;DR: In this paper, the wave energy resources in the Black Sea basin were evaluated and a wave prediction system was implemented based on the simulating waves near-shore model, which is used for both wave generation and near-shallow transformation.
Abstract: The present work aims to evaluate the wave energy resources in the Black Sea basin. The study is focused on the western part of the sea, which is traditionally considered as being more energetic. In order to give a first perspective of the wave climate, a medium-term wave analysis was carried out using in situ measured data. As a further step, a wave prediction system was implemented for the Black Sea. This was based on the simulating waves near-shore model, which is used for both wave generation and near-shore transformation. This methodology has the advantage that a single model covers the full scale of the modelling process. Various tests were performed considering data measured at three different locations. Special attention was paid to the whitecapping process, which is still widely considered to be the weak link in deep water wave modelling. Comparisons carried out against measured data show that the wave prediction system generally provides reliable results, especially in terms of significant wave heights and mean periods. By increasing the resolution in geographical space, the field distributions of wave energy were analysed for both high and average wave conditions. The analysis and the wave prediction system developed are a prerequisite for further investigations extended in time and with increased resolution in the near-shore direction.

TL;DR: In this article, a three-dimensional morphodynamic model of sequential beach changes is presented, which is based on variations in breaker wave power generating a predictable sequence of beach conditions and is applied to explain temporal, spatial and global variations In beach morphodynamlcs.
Abstract: A three-dimensional morphodynamic model of sequential beach changes Is presented. The model Is based on variations in breaker wave power generating a predictable sequence of beach conditions. The spectrum of beach conditions from fully eroded-dissipatlve to fully accreted reflective is characterised by ten beach-stages. Using the breaker wave power to beach-stage relationship the model Is applied to explain temporal, spatial and global variations In beach morphodynamlcs.

TL;DR: In this article, the effect of placing projecting sidewalls in front of the column was investigated, for different boundary conditions regarding the regions between the absorber and the channel walls, and it was shown that the projecting sidewall can improve the wave power absorption.
Abstract: Wave-power absorption by an oscillating water column in a channel is studied within linear theory, and for different boundary conditions regarding the regions between the absorber and the channel walls. Particular attention is given to the effect of placing projecting sidewalls in front of the column.
