Coastal lagoons are fragile ecosystems that account for 13-15 percent of the world’s littoral zone. Coastal lagoons constitute an essential environmental reservoir for fluvial sediments due to their capacity to retain them and also the accompanied elemental pollutants.In recent times it has been a common practice to redistribute large amount of coastal sediments for beach nourishment projects to combat shoreline retreat. The problem of beach/shoreline recession/erosion are as a result escalating impacts of emerging global geophysical changes, such as rising sea levels, and coastal development. This book examines the environmental effects of engineered solutions of massive dredge-and-fill methods which have been adopted worldwide in regard to the issue of shoreline erosion.
