The present research performs a comparative analysis of the hydraulic behavior of a thin-walled v-notch weir, specifically the hydraulic load, between an experimental test carried out in the hydraulics laboratory of the Universidad Peruana de Ciencias Aplicadas (UPC) and a numerical model to determine their similarity and future applications in the field. The numerical model was developed with the Computational Fluid Dynamics - CFD technique using AutoCAD software for the geometry elaboration, Salome for the creation of the mesh and OpenFoam for the numerical modeling and its subsequent visualization. Four different flow rates were chosen for comparison (10, 15, 20 and 25 m3/h) for both cases and two mesh sizes for the computational modeling (0.007-0.03 and 0.01-0.05). The variable measured and analyzed is the hydraulic load or head upstream of the apex. The results were compared through five statistical formulas Nash Sutcliffe coefficient, coefficient of determination, root mean square error, mean absolute percentage error and mean absolute error. Both mesh sizes obtained positive results, with values close to those observed in the experimental trial, but the 0.01-0.05 mesh size performed slightly better in the statistical formulas with a mean absolute error of 0.00769150 and a mean absolute percentage error of 8.13%.
