Over the past 30 years, up to half of the storms that hit Vietnam have caused a water level rise of over 1 m and 11% of storms have raised sea levels above 2 m. In very special circumstances, typhoons can form up to several meters high. In some coastal areas, typhoons create waves and shorten the coastline. As a consequence, storm surges cause deep water intrusion into the land. Typhoons caused huge damage to fishermen fishing at sea, destroying aquaculture facilities, destroying dyke systems to prevent salinisation, bringing saltwater intrusion into the rice fields and coastal residential areas. sea.
