Abstract
This study investigates the flow characteristics over a Crump weir in a 2-meter open-channel flume using particle tracking and video frame-per-second (FPS) analysis. Sand particles were introduced into the flow as tracers, and their movements were recorded at 30 FPS to determine the velocity distribution across varying depths and locations. The experimental data were used to compute flow velocities, which were subsequently validated against theoretical equations, including Bernoulli’s equation and empirical weir flow equations. The results show a general increase in flow velocity with depth, with notable variations influenced by channel geometry and surface friction. The comparison between experimental and theoretical velocities revealed minimal percentage errors, demonstrating the accuracy of particle tracking in measuring velocity in open channels. This method provides a reliable and practical approach to studying flow behavior in hydraulic structures, with significant implications for hydraulic design and analysis.
