Increasing population, expanding industry and commerce, and tourism are placing added pressures on an already highly-utilized coastal zone. This book, through a series of case studies, illustrates the variety of changes already made along the coastlines of the world. The examples used are mainly from China, Japan, The Netherlands, and the United States, all countries with extensively engineered shorelines. Modifications emphasized include those associated with protection against coastal erosion, building of artificial beaches and islands, reclamation for aquaculture and agriculture, and the construction of harbors. The information in this book should be useful for all planners and engineers involved in the construction of coastal engineering works and for students interested in coastal modification.
