    Abstract

    This paper reports on an experimental test program investigating the motion and entrainment of flow-entrained debris. The motion of debris in large scale hydraulic events can cause severe damage to the impacted communities: the dynamic characteristics of the debris' motion is crucial in identifying high-risk areas in affected communities. Determining the motion of flow-entrained debris has been historically difficult to quantify as many traditional techniques, such as post-mortem site assessment, cannot provide sufficient information about the kinematic and environmental conditions that affect the debris motion. This paper presents a novel non-invasive system for tracking the 6 degrees-of-freedom debris motion. The experiments examined the effect of various debris configurations on their entrainment as well as their overall motion. Using video footage, the debris entrainment mechanisms and surrounding flow features common to all experiments were examined and using this tracking system, the motion of the debris was accurately tracked and further used to validate other debris spreading observed in real field conditions.
