Geobag (sand-filled geotextile bags) revetments have recently emerged as long-term riverbank protection measures in developing countries; however, their performance is still not well understood. The hydraulic stability of geobag used for has been studied within an extensive laboratory programme to improve our understanding the complete failure processes revetments. A 1:10 scale distorted physic...

The development of coastal regions combined with rising sea levels is leading to an increasing risk flooding caused by wave overtopping natural beaches and engineered structures. Previous measurements have been obtained for static structures using fixed current meters depth sensors or tanks. These are unsuitable dynamically stable protection however, because the geometry these expected evolve u...

Wave absorbers installed in front of revetments are effective reducing wave overtopping and inundation caused by periodic waves. The absorbers’ mechanism long-period waves such as tsunamis storm surges is not clearly understood. This study conducted a physical modeling test numerical analysis based on large eddy simulation model using in-house code to examine the characteristics according revet...
