Book Description
Beaches in Japan have been eroding since the 1970s as a result of the artificial land alterations. Approximately 3000 fishing ports and 1000 commercial ports have been built nationwide, as well as 2532 large dams being constructed in the upstream basins of large rivers. Due to the port and dam developments, fluvial sand supply has significantly reduced resulting in shoreline recession around the river mouths. Continuous sand supply along the coastline has also been obstructed by the port breakwaters. The formation of wave shelter zone by the port breakwaters induce longshore sand transport, thereby leading to an accretion of large amount of sand in the wave shelter zone and erosion in the surrounding area. Thus, almost all causes of the beach erosion in Japan are due to anthropogenic factors. The exact situation of the beach erosion has never been clear in literatures that are written in Japanese, or in English. Coastal engineers can and should learn from these results, otherwise the same situation and problems, which were induced by excessive coastal development without protection measures and due attention given to nearby coasts, will recur throughout the world.Textbooks on coastal engineering, that were already published, describe only the theoretical fundamentals of the subject, but lack the practical perspectives and field studies. The book examines many coastal areas as examples, highlighting the various erosion factors which should be avoided elsewhere globally. This book was first published in Japanese in 2004, and was translated into English by the present author.

Book Description
Beaches in Japan have been eroding since the 1970s because of artificial land alterations and unsustainable coastal development. Almost all causes of the beach erosion in Japan are due to anthropogenic factors — as a result of human activity. This book presents the state of the beaches throughout Japan, looking at the current reality and the classification of causes of beach erosion using real-life, illustrated examples. It then goes on to look at practical models which can be used to predict changes to different types of beaches, and concludes with investigation of beach erosion as a wider structural problem. Lessons learnt show the manner in which excessive coastal development without clearly identified measures for beach protection can have widespread global ramifications.This second edition presents new findings from field studies carried out on Japanese beaches, along with the development and improvement of the numerical model presented previously. In addition to the first edition, six new examples of the beach erosion in Japan are included, as is new analysis of the BG model (a model for predicting based on Bagnold's concept), which can be applicable to various field problems.Originally published in Japanese (2004), this updated version gives clear practical guidance to coastal engineers working to prevent irreversible beach erosion and sustainable coastal development policy.

Book Description
This book covers the gamut of coastal hazards that result from short-term low-frequency events and have high-magnitude and far-reaching impacts on coastal zones the world over. Much of the world’s population now lives in low-lying coastal zones that are inherently vulnerable to natural hazards such as flooding from hurricanes, tropical storms and northeastern storm surges; shoreline (beach and dune) erosion; cliff and bluff failures; and saltwater intrusion in coastal aquifers used for drinking water supplies. In addition to the usual range of hydrometeorological disasters in coastal zones, this book covers tsunami impacts and warning systems as well as global perspectives of sea-level rise impacts and human perceptions of potential vulnerabilities resulting from rip currents that cause many drownings each year on beaches. Today, the use of numerical models that help predict vulnerabilities and provide a basis for shore protection measures is important in modern scientific and engineering systems. Final considerations focus on human actions in the form of the urbanization and industrialization of the coast, shore protection measures, and indicate how environmental degradation around coastal conurbations exacerbates the potential for unwanted impacts. Strategies for environmental management in coastal zones, from low-lying wetlands to high cliffs and rocky promontories, are highlighted as a means of living in harmony with Nature and not trying to conquer it.

Book Description
The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.
