Experimental Velocity and Depth Data for Validation of Turbulent Shallow Water Flow Models

DescriptionThis dataset contains experimental measurements of velocity and water depth in three hydraulic configurations, used for the validation of a second-order mean gradient finite volume scheme for turbulent shallow water flows. The data were obtained in laboratory experiments conducted at the Hydraulics Laboratory of the University of A Coruña (Spain). The dataset includes: 1_BSExp_Vel.vtp – Velocity vector field measured in an open-channel sudden expansion experiment. 2_FlocExp_Vel.vtu – Velocity vector field measured in a two-tank settling facility. 3_EscPcsExp_Depths.vtu – Water depth field measured in a fishway configuration. 4_EscPcsExp_Vel.vtu – Velocity vector field measured in the same fishway configuration. Measurements were performed using a Sontek Acoustic Doppler Velocimeter (ADV), with high spatial resolution and sampling frequency, ensuring minimal disturbance to the flow. The files are provided in VTK format (.vtp and .vtu) for direct use in scientific visualization and post-processing software such as ParaView or VisIt. These datasets allow direct comparison between numerical results and experimental measurements, particularly for the evaluation of flow recirculation, reattachment lengths, vortex formation, and velocity magnitude distributions in turbulent shallow water conditions.
