Wave Overtopping | Vibepedia

Wave overtopping is the phenomenon where ocean waves surge over the crest of coastal defense structures like dikes, breakwaters, and seawalls. Quantified as the volume of water per second per meter of structure length, it's a critical metric in coastal engineering, directly impacting the safety and integrity of shorelines. While a certain level of overtopping might be tolerated or even harnessed for wave energy generation, excessive overtopping, often triggered by extreme weather events like storms coinciding with high tides, poses significant risks. These risks include damage to the landward side of the structure, potential inundation of protected areas, and erosion, which can ultimately lead to catastrophic failure. Understanding and predicting overtopping is therefore paramount for designing resilient coastal infrastructure in an era of rising sea levels and intensifying storm activity.
