This simple Flash animation contrasts winter and summer sediment transport. During the summer, lower energy waves with longer wavelengths allow sediment to accumulate on the beach face. In contrast, during winter storms higher energy waves with shorter wavelengths deposit sediment as offshore bars. This visualization is from the animations section of Chapter 14 (Waves, Beaches, and Coasts) of the Online Learning Center for the McGraw-Hill textbook Physical Geology, 9th edition (ISBN: 0072402466) by Plummer, McGeary and Carlson.
