Abstract:

The use of a 3D Scanner allowed the acquisition of dam breach geometry on a physical model. This technique is widely used in interactive movement entertainment and was adapted for this study’s aims. The conceived apparatus collected breach geometry from a physical model built to evaluate a channel’s cascade dam break. The 3D Scanner mapped breach sur- faces and allowed the input on image processing software to generate its digital surface and elevation contours, reducing measurement errors since it is a non-contact method. An apparatus was then developed to enable accurate scanning since this feature’s original function was motion detection. The apparatus consisted of a platform assembled on rails, installed over channel walls, supporting a Kinect II (Microsoft Corporation ® 3D Scanner), connected to a notebook.
