Numerical models trying to faithfully represent the movement of floating bodies transport in open-channel flow require experimental data for validation. In order to provide an adequate dataset, flume experiments were carried out to analyse the transport of singular and grouped rigid bodies floating on the water surface. Both cylindrical and spherical samples were employed: they were released in a rectangular channel under steady conditions in one-dimensional (plain channel) and two-dimensional (2D) configurations using one rectangular side obstacle, one smooth side obstacle or two rectangular alternate obstacles. The outcomes of the experiments are the planar displacement and the rotation of the samples, which are related to the flow field in the different configurations. The detailed experimental analysis of the floating body motion provides information for the calibration of numerical models simulating floating bodies transport. This dataset is thus employed for the validation of the Eulerian–Lagrangian model ORSA2D_WT, highlighting its strengths and improvable aspects. Similar applications could be carried out with any 2D model which performs the simulation of discrete elements moving on the water surface.

试图真实地表示明渠流动中浮体运输运动的数值模型需要实验数据进行验证。为了提供足够的数据集，进行了水槽实验以分析漂浮在水面上的奇异和成组刚体的传输。圆柱形和球形样品均被使用：使用一个矩形侧面障碍物，一个光滑侧面障碍物或两个矩形交替障碍物，将它们在稳定条件下在矩形通道中以一维（普通通道）和二维（2D）配置释放。实验的结果是样品的平面位移和旋转，这与不同配置下的流场有关。浮体运动的详细实验分析为模拟浮体运输的数值模型的校准提供了信息。因此，该数据集用于验证欧拉-拉格朗日模型ORSA2D_WT，突出了其优势和可改进的方面。任何二维模型都可以执行类似的应用程序，该模型可以对在水面上移动的离散元素进行仿真。
