ASCE STUDY FINDS SEAWALLS WERE EFFECTIVE IN TSUNAMI

Seawalls were able to slow the force of the December 26, 2004 Indian Ocean tsunami, according to a draft study by the American Society of Civil Engineers. Damage at five beaches in Sri Lanka, India and Thailand was survey by ASCEs Coasts, Oceans, Ports and Rivers Institute (COPRI). It was found that seawalls that were there reduced damage and saved lives, suggesting that additional seawall construction could have saved more lives and property and should be built. In one location, a sand dune offered a great deal of protection. Elevated buildings fared better because the brunt of the force passed under them. Buildings whose foundations were at the same height as the seawall, though, were completely destroyed. Bridges were particularly hard hit in damage suggestive of what happens in a hurricane surge. If there had been earlier, more accurate warnings, perhaps as many as 75 percent of the lives lost could have been saved because safer ground was usually not more than a kilometer away.
