The article discusses how wind-blown sand affects the shape of man-made dunes at the Hondsbossche Dunes in the Netherlands. By studying different dune shapes, researchers found that dune growth depends on factors like wind patterns and the dune's design. They used a model to predict how sand moves and accumulates on the dunes. The study shows that both wind and ocean processes play a role in shaping man-made dunes, similar to natural dunes. Monitoring and modeling these dunes will help improve how we design them in the future.
