Also covers shoreline characteristics, currents, sea barriers, tides, and how the greenhouse effect could impact sea level and coastal lands."@en . . . . .

Topics include: tsunamis, erosion, tidal action, wave refraction, sedimentary (sand) transport and deposition, longshore currents and drift, effects of human intervention on this environment (dams, breakwaters, sea-walls), and sea level changes from greenhouse effect."@en . . . . . . . . . .
