Figure 1. Sand dunes along the Florida panhandle.Sand dunes are a natural phenomena that occur along beach shores, bay shores, and coastal inlets. This piece was written for the physical geographer to learn about how sand dunes are formed and the parts of the sand dunes that are protected and not protected by human landscapes. The author focuses on coastal regions of the Netherlands and the U.S. Atlantic primarily because these are flat regions. Sand dunes are used as protected barriers against natural storms and human landscapes have added to altering the shape, along with wave production and winds, in which cause some areas of the sand dune to become intolerable.
I think the author was trying to send a message to his readers that sand dunes are actually an important part of the natural, physical landscape. Not many people consider sand dunes important. They do protect from floods of coastal regions in some extent. Sand dunes, especially in two particular areas; the primary and secondary, are off limits and bridges are built over them for their protection. In other words, lets stop the building of homes over these sanes dunes and build further inland for more protection. In an event of a severe storm or hurricane, a house built on a sand dune is more likely to suffer maximum damage than if it were built more inland. There is a reason why the primary sand dunes are fenced off to keep out, to become a better protection barrier.

I remember I time in Panama City, FL which happens to be in the Panhandle , when the sand dunes were 25-50 feet high. Of-course that was 20 years ago, now there are practically no dunes left, either by hurricane erosion or by idiot building contractors. The ocean's basically reclaiming the land. I'm sure you've seen what it looks like after a heavy storm on Jax beach, Fernandia use to really look like shit after a storm. It's sad but a reality and no matter how many times people are told not to build "here" or "there" they keep on doing it anyway, idiots!
Hey remember the sand dunes we saw last semester in Fallon, those were neat. Rememebr the story behind it and how they travel from on area to another.
