Measurements of debris flow entrainment and dynamics

The mechanisms of debris flows and their interaction with mitigation structures are still not well understood. Among the research challenges, only few entrainment measurements available in literature, as is often masked by deposition on top. In this paper, we present a simple, cheap, effective method to measure depths. Flume experiments have therefore been performed assess influence initial flow volume an upstream flexible barrier entrainment. To better understand dynamics, basal stresses measured. A high degree liquefaction at base observed. reduce has also studied. compact was installed part channel observed deflect along curvilinear path. High normal measured overflow, which caused additional centrifugal from overflow. results flume tests suggest that may significantly dynamics both downstream barrier.
