Küstensturmfluten

Küstensturmfluten, also known as storm surges, are a significant coastal hazard. They occur when a severe storm, such as a hurricane or a strong extratropical cyclone, drives seawater towards the coast. This phenomenon is primarily caused by a combination of factors: strong onshore winds pushing the water surface, a drop in atmospheric pressure associated with the storm allowing the sea level to rise slightly, and in some cases, the angle of the coastline or the shape of the seabed can further amplify the surge.

The impact of a Küstensturmflut can be devastating. Coastal communities can experience widespread flooding, leading to damage to infrastructure, homes, and businesses. The surge can erode beaches and dunes, altering the natural landscape. In addition, the combination of high winds and storm surge can generate powerful waves, increasing the destructive potential. The severity of a storm surge depends on the intensity of the storm, its speed, the angle of approach to the coast, and the specific bathymetry and topography of the affected area. Coastal defenses, such as sea walls and dikes, are often employed to mitigate the effects of storm surges, but they can be overtopped or breached during extreme events. Monitoring and early warning systems are crucial for protecting lives and property in vulnerable coastal regions.
