Specific Impacts of Storm Tides
Storm tides are characterized by extreme water levels, strong winds, high waves and strong
forces which affect the coastline. These different factors are the reason for the high damage
potential of storm tides. In addition to coastal erosion, inundation of usually dry areas
entails a high damage potential.
In this respect fresh water resources are extremely vulnerable to inundations. Inundating salt water pollutes the soil (reducing the agricultural productivity) and can infiltrate
