In light of the forebay a lateral pump station in Shaanxi Province, numerical simulation and engineering tests were employed to analyze correlation between formation multiple vortices sediment deposition forebay. Building upon this foundation, total 24 distinct rectification measures proposed scrutinize alteration flow regime within forebay, followed by an test validate optimal scheme absence measures. The findings from consistent with outcomes simulation. This marked inaugural proposition trapezoidal array clapboard By adjusting position, rotating angle, selecting 24, velocity uniformity at section C1-2 reached 93.16%, deflection angle measured 94.32°, vortex area reduction rate was 87.73%, significantly mitigating impact on section. Within C1-3, attained 96.58%, 86.43°, amounted 81.26%. Through analysis these two sections, scheme's accuracy validated. Additionally, thickness decreased 2.39 m under thus ensuring favorable operational conditions for inlet station.
