This is one design solution to mitigate damage to facilities from overwashing waves at Roi-Namur, the second largest island of the Kwajalein Atoll in the western central Pacific Ocean. On Jan. 20, 2024, a high water-level and wave event struck the island of Roi-Namur causing significant damage to infrastructure from direct wave impacts and inundation flooding. During the six-hour event, waves periodically washed overland, striking buildings and pushing tens of thousands of cubic meters of water onto the island. Debris such as sand, gravel, corals, large rocks and chunks of concrete that was previously located on the offshore reef and shoreline was pushed by waves hundreds of feet inland.
