The modification of the surface velocity field of the weakly undulatingflow in a reach of the Suquía River (Córdoba city, Argentina) due to theplacement of a bridge was investigated in a physical model. Measurements usingLarge-ScaleParticle Image Velocimetry (LSPIV) allowedevaluating how the hydraulic structure changes the size, shape, wavelength, andrelative position to river centerline of the wave train downstream of thefirst ridge of the weak undular jump. Analysis and discussion of results in terms of the dimensionlessparameters reported in the literature (obtained from laboratory studies) are offered. Results show that LSPIV is a reliable,fast low-costtool to gather valuable information regardingthe surficialflow field at the physical model scale in the presenceof a weakly undular flow.
