This article provides an overview of coastal dynamics and shoreline protection. It covers topics such as coastal erosion, beach morphology, wave analysis, sea level variability, sediment transport, and shoreline modeling. The researchers discuss the causes of coastal erosion, different types of protection systems, and the design of structures to protect coastlines. Key findings include the importance of understanding sediment transport, the impact of wave energy on shorelines, and the effectiveness of various shoreline protection measures.
