Abstract
In this study, to investigate the effect of the array of cylindrical baffles on debris flow impact load, a series of small-scale tests were conducted according to varying row numbers of installed baffles in the flume. After the test, the behavior of debris flow interacting with baffles during the flow process was investigated. Based on the results, the influence varying velocity and flow depth on Froude number and dynamic pressure coefficient were analyzed. Test results showed that the greatest peak impact load occurred at the second row of baffle arrays. The dynamic pressure coefficient was also estimated by suggested equation and compared with previous studies.
