This dataset contains the results from the experimental tests carried out at the hydraulics laboratory of the Civil Engineering School, at University of A Coruña (Spain), as part of the VAMONOS (Vertically-averaged models for non-hydrostatic flows) project (CTM2017-85171-C2-2-R). The aim of the project is the development of enhanced 2D river flow models including additional terms to account for non-hydrostatic pressure and mixed flow conditions around hydraulic structures. This data package includes experimental results on 4 bridge geometries that were tested in an open channel. The experimental facility consists of a 15 m flume with a square cross-section of 0.5 x 0.5 m. Water depths were measured with an automatic positioner on a grid of approximately 117 points. In whole, 32 experimental tests have been carried out under different flow conditions. This dataset is structured in the following pdf documents and folders: . This file summarizes all the experimental tests. . This file includes information about the experimental facilities, the test conditions and the uploaded files. .pdf. This file includes a 3D representation of the water depths measured in each experimental test. This folder includes the raw data registered in the experimental tests. Matlab_files. This folder contains three Matlab files (.m) that can be used to process the raw data, to plot the results and to generate a document with information about the test. Processed_data. This folder contains, for each structure, a pdf with the structure geometry and a text file per test with the water surface elevations measured. Those interested in experimental data for the calibration of numerical models or the analysis of empirical discharge rating curves, are suggested to work only with the data included in the folder Processed_data. Further details on the experimental setup are given in the document Data_package_description.pdf.
