Sea level rise is one of the main problems affecting coastal zones on a global scale. It is not as simple as that the coast will just drown as if the coast is in a bath tub with increasing water level, since the coast will respond in a dynamic sense. Actually, a natural coast will adapt to sea level rise, the coast will want to keep pace with sea level rise, raising its profile relative to the sea level. A perfect response to rising sea levels! In order to do this a sediment budget deficit is created however. How does this actually work? Learn this and more by reading the document “The Bruun Rule: its validity and its limitation”.
