Abstract—Groins are a kind of structures which constructed to prevent the coastal areas from erosion and to manage the direction of flow. However, the groin body and related flow features are the main causes of local corrosion. In this study, we investigate the flow patterns around refractive and right-angle groins. The flow characteristics around a refractive groin are compared numerically and study to achieve a reliable right-angle groin of various projected lengths. The results indicate that the relation between the thalweg height and geometry of the channel and groin length can be approximated using linear formulas regardless of internal celerity in the flow region.
