For the Instructor
These student materials complement the Coastal Processes, Hazards and Society Instructor Materials. If you would like your students to have access to the student materials, we suggest you either point them at the Student Version which omits the framing pages with information designed for faculty (and this box). Or you can download these pages in several formats that you can include in your course website or local Learning Managment System.

Because barrier islands are built by waves, they do not develop in tide-dominated environments. Waves are responsible for the longshore transport of sediment, and it is this transport that drives the deposition of sediment to create elongated features consisting of sandy barrier islands. There are, however, numerous examples of barrier islands within mixed-energy as well as wave dominated environments. In fact, the two fundamental types of barrier islands are recognized as wave-dominated and mixed energy barriers.
