Experimental Investigation of the flow pattern in the Embayment

Embayment or Side-cavities are built as a natural or artificial complication, which generally has shallow flow conditions, as affecting the hydraulic conditions of the flow. These complications affect important hydrodynamic processes that play an important role in the general behavior of the flow by creating secondary structures and shear layers. Therefore, the experiments were performed in an Embayment with a size of 0.3 * 0.3 m, adjacent to a canal 0.5 m wide. Speed measurements in the defined network were performed using the Vectrino 3D Velocimeter. Observational results confirmed the existence of a large-scale gyre in the interior of the embayment. Further analysis of the data showed that the velocity in different directions is affected by flow of the main canal and with increasing current in the main canal flow, the velocity in the embayment also increases. Also, the results showed that at a constant flow through the main channel, with increasing flow depth, the speed in the outer half of the embayment decreases as the main channel but in the inner half, the speed increases with increasing depth. This indicates as increasing depth, a greater advancing of the stream into the embayment would be observed.
