EXPERIMENTAL INVESTIGATION OF TSUNAMI WATERBORNE DEBRIS IMPACT ON STRUCTURES
Keywords:Tsunami, Hydraulic bore, Water born debris, Experimental modeling
Tsunamis and hurricanes cause a lot of damage to structures. The water-borne debris that is
produced during these natural disasters can cause a considerable damage to the many structures if they have
not been constructed for such loads. Tsunami field survey observations have indicated that the damage is
aggravated by heavy objects like wooden logs, automobiles, boats, storage barrels and other containers. This
paper presented the results of experimental study for the quantification of the debris impact force on the
structures. Moreover, it studied the formulas, which have been specified in the recently published tsunamiresistant engineering design guidelines (FEMA P-646, 2012) and the Coastal Construction Manual (FEMA P55, 2011) with the results of experiment.
