Calibration and Validation of 3D Numerical Models of a Straight Channel with Leaky Barriers

In this contribution, two 3D numerical models are tested using laboratory records to properly calibrate and validate these models.1D numerical techniques are also used for this purpose.Mesh sensitivity analyses, different roughness coefficients, and Acoustic Doppler Velocimetry (ADV) records were applied to increase the reliability of the 3D model results.Thanks to these analyses, the output of the models can be used for design purposes to properly assign the geometry of leaky barriers in real world cases to enhance flood resilience above all in urban areas.
