Abstract: The present study investigates the effects of side, vertical, and a combination of both side and vertical suction seepage on the flow patterns in a laboratory flume. To examine streamwise, transverse, and vertical components, an Acoustic Doppler Velocimeter (ADV) is used to analyze the complete velocity readings. The results demonstrate that near-bed velocity is relatively higher under suction seepage conditions than in other conditions. The impact of side suction seepage is primarily in the lower area next to the side wall. The vertical and transverse components of the flow mostly stay negative (downward and towards the wall). Combined suction seepage has a high velocity in the lower zone close to the side wall. Using velocity vector plots, it is observed how seepage affects wake and primary vortices, causing disruptions to the flow upstream and downstream of the abutment. These understandings are essential for creating hydraulic structures that are stable and long-lasting by better withstanding these flow dynamics.
