On occasions, sandbag revetments are temporarily applied to armour sandy beaches from erosion.Nevertheless, an empirical formula to determine the Elevation Assembly wave run -up height on sandbag slopes has not been available heretofore.In this study a wave run-up formula which considers the roughness of slope surfaces is proposed for the case of s
Based on the decorrelation calculation of diffusion ultrasound in time-frequency domain, this paper discusses the repeatability and potential significance of Disturbance Sensitive Zone (DSZ) in time-frequency domain.The experimental study of Barely Visible Impact Damage (BVID) on Carbon Fiber Reinforced Polymer (CFRP) is carried out.The decorrelati
