The Seawall experiment in the Large Wave Flume at Oregon State University's O.H. Hinsdale Wave Research Laboratory. Researchers vary the seawall height by changing the number of wooden boards in the system from 1 to 6 (0.04m-0.24m).

A wave impacts a seawall, leading to skyward deflection of momentum. Over the range of wave heights tested, the 0.24-meter-high seawall caused force reductions ranging from 45 to 85 percent.

Photo of a building in Khoa Lak, Thailand, destroyed by the 2004 tsunami.

This building, located in Khoa Lak, Thailand, was destroyed by the 2004 tsunami. Note that while the frame and roof are gone, the structural elements (columns) survived. By measuring the column diameter and assessing the amount and type of reinforcement, Mary Beth Oshnack and her colleague at the University of Notre Dame, Emily Kunen (left), obtained detailed input for structural models.
