<p>Gabion walls (4,30) built into the sea as tsunami barriers, extending at least 50m up to 4km below sea level. Vertical walls extending above sea level, preferably protected with hanging triangular structures as surge stoppers (41), with stabilization landward (18), to replace conventional dikes and levees and to save land areas. Vertical walls of fences (31, 32) extending above sea level, which are circular and filled with rocks, surround pillars to protect off-shore platforms, windpower plants, bridge pillars and other submarine structures.</p> |
