ESTIMATION OF WAVE POWER AND RECENT DECADAL CHANGES IN BULGARIAN BLACK SEA NEARSHORE AREA
Abstract
The study deals with estimation of theoretical wave power resources and their spatial variability in transitional waters along the Bulgarian Black Sea coast. It is based on wave climate data obtained by means of hindcast of wave conditions during 2013-2022. Numerical simulations were performed using the third-generation spectral wave model SWAN and the theoretical wave power was computed using the spectral output in terms of energy transport per unit of the wave crest length. Estimates for wave power means and maxima as well as for the total wave energy are presented for twenty locations along the study area. They assert the high spatial variability of wave power as well as its slight decrease compared to the previous decade. Results point out changes in wave energy potential compared to previous decade expressed in a minor decrease along almost the entire Bulgarian Black Sea nearshore area.
