Wave Transmission over Submerged Breakwaters

Abstract

This study is based on a 2B small-scale experimental investigation carried out to examine the effects of submerged breakwaters on wave transmission. In the study, 60 different submerged breakwater models were tested under four different hydrodynamic conditions, and the effects of breakwater height and crest width on wave transmission were evaluated. The experimental data were compared with existing wave transmission models developed by Meer, d’Angremond et al., Seabrook et al., Friebel et al., and Van Gent et al. [1-5] The study particularly emphasized that larger submerged breakwaters, with both higher and wider crests, contributed significantly to the reduction of transmitted wave height. Among the various formulations tested, the Van Gent [5] formula showed the highest consistency with the experimental results, highlighting the importance of both geometric parameters and hydrodynamic conditions in optimizing coastal protection strategies.

Batık Dalgakıranlarda Dalga İletimi

Abstract

Bu çalışma, batık dalgakıranların dalga iletimi üzerindeki etkilerini incelemek amacıyla yapılan 2B küçük ölçekli deneysel bir çalışmaya dayanmaktadır. Çalışmada, 15 farklı batık dalgakıran kesiti, dört farklı hidrodinamik koşul altında test edilerek, dalgakıran yüksekliği ve kret genişliğinin dalga iletimi üzerindeki etkileri değerlendirilmiştir. Deneysel veriler, Van der Meer, d'Angremond vd., Seabrook vd., Friebel vd. ve Van Gent vd. [1-5] tarafından geliştirilen mevcut dalga iletimi modelleriyle karşılaştırılmıştır. Çalışma özellikle hem daha yüksek hem de daha geniş kretli olan daha büyük batık dalgakıranların iletilen dalga yüksekliğinde daha önemli bir azalmaya katkıda bulunduğunu vurgulamıştır. Test edilen çeşitli formülasyonlar arasında Van Gent [5] formülü deneysel sonuçlarla en yüksek uyumu göstermiş ve kıyı koruma stratejilerinin optimize edilmesinde hem geometrik parametrelerin hem de hidrodinamik koşulların önemini vurgulamıştır.
