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.

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.

Headland-bay beaches (HBBs) are ubiquitous in coastal environment. They exist around the world naturally or artificially as byproduct of engineering project. Though in various shapes, sizes and stability, a HBB in static equilibrium not only is a delight for visitors, but also offers hope for better beach protection, restoration, recreation, and shoreline management. With an empirical parabolic model now available, the stability of an existing HBB can be verified, the future bay shape downdrift of a harbor can be predefined, and a stable HBB can be designed.Although a plethora of books are available for coastal and ocean engineering and geomorphology, only a countable few have covered engineering applications of HBBs. On the contrary, this book with focus on the HBBs in static equilibrium aims to offer a comprehensive volume with knowledge and applications for coastal scientists, engineers, managers, students, and the general public interested in HBBs. Useful software tools for HBBs (MEPBAY, MeePaSoL, and SMC) are introduced in the book to aid in applications.The authors have set out to make this book the first unique publication on HBBs, by bringing together the old coastal geomorphic knowledge and new concepts for static bay beaches. This book also provides numerous examples using the static bay beach concept to assist coastal scientists and engineers on planning and pre-design of a stable HBB, and for experimentalists, consultants, and numerical modelers to alleviate the burden of comparing planning options and conducting laborious physical experiments on coastal sedimentation problems.

This book explores contemporary tourism and coastal developments in Hyogo, Japan—the nation’s only non-peninsular prefecture bordering two oceans. In striking detail, Dr. Lesley Crowe-Delaney skillfully contextualizes tourism industry and policy; illustrates coastal urban and rural development dichotomies; discusses hegemonic devices of nationalism, nature, authenticity and tradition, as embedded in tourism strategies; and highlights the nuances of Japan’s distinctive administrative systems and specific approaches to tourism. Crowe-Delaney reveals the strains placed on coastal communities when fisheries, tourism, sustainable development, and national policies intersect, offering readers an enlightening discourse of the potency of tourism as a rejuvenation tool.

Sandy beaches are the most abundant coastal environments worldwide, which have an undeniable and unique ecological value. Presently, they are amongst the most endangered ecosystems in the biosphere, mainly due to the influence of several human activities. In this book, renowned scientists from around the world describe key attributes of sandy beaches and highlight the problems which impact them. Specific tools encompassing the physical environment and the biota are pointed out, at different levels of ecological organization. The book also covers suitable management, conservation programmes and respective actions, where ecologic, economic and social dimensions are comprehensively integrated.

This book contains six chapters covering the sedimentary processes with examples from Asia, Turkey, and Nigeria. The book focuses on the geological characteristics, beach processes, coastal and lacustrine sedimentary archives, and the role of mangroves in controlling coastal sedimentation. In more detail, these topics are pertaining to the geological characteristics and the production response of a reservoir located offshore the Niger Delta (Nigeria), the coastal lacustrine geo-archives with the example of the Lake Bafa (Turkey), the sedimentary processes in the riparian zone of the Ruxi Tributary Channel (Three Gorges Reservoir, China), the beach morphological changes studied by means of a contour-line change model and finally, the role of the mangroves in controlling the sedimentary accretion of coastal and marine environments with the regional example of the south-eastern Asia.

The authors have developed models for predicting beach changes applicable to various problems on real coasts. One of them is the contour-line-change model to predict long-term beach changes caused by the imbalance in longshore sand transport, which is a kind of N-line model. Because the calculation of the nearshore current is not needed in this model, and the computational load is small, it has an advantage in the prediction of long-term topographic changes on an extensive coast. However, the handling of boundary conditions becomes difficult when offshore coastal structures are constructed in a complicated manner, and in this regard the so-called 3D model has an advantage. Taking this point into account, the authors developed a morphodynamic model (BG model) by applying the concept of the equilibrium slope and the energetics approach, in which depth changes on 2D horizontal grids are calculated.

This regional study includes the People's Republic of China, Japan, the Republic of Korea, and Mongolia and examines how strategies for adapting to climate change up to 2050 can be combined with measures to reduce greenhouse gas emissions in East Asia. Besides discussing climate model results for costs of adaptation in infrastructure, coastal protection, and agriculture, the study estimates costs for sector-specific mitigation options and the total abatement potential for 2020 and 2030. Long-term strategies for addressing the impacts of climate change in East Asia are explored with a focus on the linkages between adaptation and mitigation taking account uncertainty about key climate variables. Finally, it discusses opportunities for enhancing the effectiveness of some critical climate change policies such as regional carbon market.
