Abstract: This study investigates the impact of cubic obstacles on the velocity behavior of water flow in open channels under varying conditions. The cubic obstacles are designed to disrupt the smooth flow of water, inducing flow separation and reattachment, which in turn affects the velocity distribution and overall stability of the flow. Utilizing three different channel slopes (S = 0°, 1.02°, and 1.4°) and three distinct flow rates (Q = 0.0035 m³/sec, Q = 0.004 m³/sec, and Q = 0.0045 m³/sec), the research focuses on the dynamics of flow separation and reattachment induced by the presence of these obstacles. The methodology involves both experimental works and computational fluid dynamics simulations to analyze the flow patterns, drag forces, and the resulting velocity profiles. Results reveal significant alterations in streamlines, with the cubic obstacles affecting not only the velocity distribution but also the overall stability of the flow. The findings highlight the critical role of slope and flow rate in influencing the interaction between fluid dynamics and channel geometry, providing insights for optimizing the design and functionality of open channels in urban drainage systems.
