Image Analysis Techniques to Characterize Scaled Embankment Failures
The present work consists in the application of image analysis techniques to characterize the failure by overtopping of a scaled embankment dam that was experimentally tested in a medium-scale facility located at the National Laboratory of Civil Engineering. These techniques were used to describe the failure of the small-scale dam by defining the 3D profile of the dam body in several time instants. This was performed with depth images and with the characterization of the surface velocities of the flow near the breach based on the application of Particle Tracking Velocimetry (PTV) algorithm. The characterization of the 3D reconstruction of the failed dam and surface velocity maps in the breach vicinity were based on the post processing analysis of high-definition (HD) digital images and depth images, strategically acquired around the dam. This work assesses the usefulness of image analysis techniques for the applications herein presented.
