Shifting sands pose new problem
With sea levels rising and coastal erosion washing away more and more sand, many beaches are now slowly disappearing.
This is such a large problem that organizations like the United Nations Educational, Scientific, and Cultural Organization (UNESCO) are researching solutions. However, the classic coastal erosion theory, the Bruun Rule, is insufficient for thorough analysis of many of the world’s beaches. Some topics, like climate change, are excluded from this traditional method, so Roshanka Ranasinghe and associates at UNESCO and TU Delft are studying the areas the Bruun Rule has left blank.
