The drag and inertia forces were assumed as the total resistance generated by the vegetation. It was found that a relatively small period tsunami wave was more destructive than a relatively large period tsunami wave of the same height, although densely grown vegetation effectively reduced the tsunami energy in the case of the small period tsunami wave. A very mild ground slope was also more vulnerable to thrashing by tsunami waves than a relatively steep ground slope. Moreover, densely growing coastal vegetation on very mild ground slope dissipated tsunami energy more efficiently than the same vegetation on relatively steep ground slope., Electronic version of an article published as Journal of Earthquake and Tsunami (JET) Year: 2008 Vol: 2 Issue: 2 (June 2008) Page: 157 - 171 10.1142/S179343110800030X (c) copyright World Scientific Publishing Company http://www.worldscinet.com/jet/, text, application/pdf}, pages = {157--171}, title = {TSUNAMI CURRENT INUNDATION OF GROUND WITH COASTAL VEGETATION EFFECTS; AN INITIAL STEP TOWARDS A NATURAL SOLUTION FOR TSUNAMI AMELIORATION}, volume = {2}, year = {2008}, yomi = {タナカ, ノリオ and タニモト, カツトシ} }
