Experimental Study on the Impact Dynamics of Cylindrical Baffles with a Rigid Barrier against Debris Flows

The use of baffle arrays behind a rigid barrier is an effective method to reduce impact force by dissipating flow energy with filtering boulders from debris flows. To prevent structural damage the barrier, appropriate configurations are needed; however, design guidelines for geometric construction have not yet been proposed. One major challenges in designing multiple structures (baffles and etc.) set up framework safe economical design. flow–structure interaction flows on affected configuration baffles installed barrier. In this study, evaluate behavior dynamic terminal after has passed through arrays, we conducted series small-scale flume tests under various heights number rows. test results revealed that installation reduced run-up height impedance induced had significant influence dissipation kinetic Moreover, additional rows produced greater reduction decreasing boulder mobility.
