Real Scale Experiments on Vehicle and Pedestrian Swept Away due to Rapid Flows

This study conducted a proto-type scale experiment to investigate a critical condition for which vehicle and pedestrian are swept away. The real scale test was designed to provide flow information with minimized scale effects. The experiments were carried out in a 3 m wide semi proto-type channel with a maximum flow rate of 10 m 3 /s that is capable of reproducing flood flows of the scale of real streams. For the vehicle test, a real sedan was put normally to the flow to simulate a vulnerable condition. For the pedestrian test, a male person walked across rapid flows. For a flood condition, flows were generated up to a water depth of 0.5 m and a flow velocity of 2 m/s, and a combination of the flow conditions were applied to find a critical condition. Experimental results from the tests will be provided and compared with theoretical approaches
