Abstract
More than half of the world population lives in the coastal zone. As a result, coastal flooding is a major threat to human society. A flood from sea may be caused by a heavy storm (storm surge), a high tide, a tsunami, or a combination of them. Knowledge in costal processes and sea wave models enables engineers to design and manage effective costal defence systems based on soft and hard engineering measures.
