This book comprises selected proceedings of the Fourth International Conference in Ocean Engineering (ICOE2018), focusing on emerging opportunities and challenges in the field of ocean engineering and offshore structures. It includes state-of-the-art content from leading international experts, making it a valuable resource for researchers and practicing engineers alike.
Coastal Dynamics 2009 is the sixth conference in a sequence of technical speciality conferences bringing together field and laboratory experimentalists, theoreticians and modelers conducting research on the dynamics of the coastal systems. The multidisciplinary Coastal Dynamics 2009 will be of interest to coastal engineers, coastal geologists, oceanographers, and related scientists. It is also of relevance to coastal specialists and managers, and to those interested in preserving coastal zones. In Coastal Dynamics 2009, special emphasis will be placed on the impacts of human activity on dynamic coastal processes.
Since the late 1970s, household archaeology has become a key theoretical and methodological framework for research on the development of permanent social inequality and complexity, as well as for understanding the social, political and economic organization of chiefdoms and states. This volume is the cumulative result of more than a decade of research focusing on household archaeology as a means to gain understanding of the evolution of social complexity, regardless of underlying economy.
The Bhagirathi-Hooghly Basin in India is one of the most densely populated regions in the world and is undergoing rapid transformation of its natural landscape induced by human interventions, such as mushrooming of dams and barrages, deforestation, and urbanization. Human activities and interventions on basin landforms and the processes that shape those landforms have accelerated at an alarming rate. This book uses spatio-temporal analysis to understand the major anthropogenic signatures on land use and land cover changes and the impact these activities have on the landforms and processes of the Bhagirathi-Hooghly River and its sub-basins. It answers the what, where, why, and how of the anthropogenic signatures involved. Recent case studies on the impact of anthropogenic signatures on fluvial forms and processes make this book a useful resource for students and researchers in the earth sciences, local governments, urban planners, and all concerned with rural developments. Features: Explores for the first time the new concept of anthropogeomorphology for the river basin—an emerging field Analyses the impact of anthropogenic activities, especially the construction of dams and reservoirs, and urbanization on major fluvial landscapes using advanced geospatial modelling techniques Investigates human interference in river systems, their effects on the dynamics of the river, and the livelihoods of the people residing along the river Addresses issues related to geology, geomorphology, geography, planning, land use, and land management areas Fills the need for data-driven governance and policy decisions for the future of urban-industrial growth in India.
The largest coastal alluvial-plain in Mexico lies along the southern Gulf Coast, almost entirely within the state of Tabasco. This plain is principally of fluvial origin, associated with the Mezcalapa and Usumacinta river systems. These two rivers, whose previous channel migrations have directly or indirectly produced most of the lowland landforms, currently share the major outlet to the Gulf, the Grijalva River. Skirting the gulfward edge of the Tabasco Plain is a narrow zone of coastal landforms comprised primarily of beach ridges plus a few groups of sand dunes. Systematic investigation of beach ridges includes profiles noting general configuration and dimension. Beaches are profiled to record sediment removal, migration, and accumulation over various time periods. Trenches and pits dug in accretionary portions of the beach profile reveal stratification sequences of inland-dipping foreset units. These deposits correlate with frequent winter-season storms, nortes, which raise Gulf levels and wave heights to construct a beach crest upon the winter beach. Intermittent washover deposition contributes sediment to the upper surface and lee side of the ridge to heighten and broaden it while producing a slow migration inland. Subsequent calm-weather accretion gradually widens the beach and eventually strands the beach ridge. Beach ridges are most numerous and the coastal zone widest where river channels course through the coastal topography and discharge into the Gulf. Adjacent to these channels, the ridge trends collectively arch seaward, fan-like, to produce a cuspate delta projecting into the Gulf. (Author).
Effective coastal engineering is expensive, but it is not as costly as neglect or ineffective intervention. Good practice needs to be based on sound principles, but theoretical work and modelling also need to be well grounded in practice, which is continuously evolving. Conceptual and detailed design has been advanced by new industry publications since the publication of the second edition. This third edition provides a number of updates: the sections on wave overtopping have been updated to reflect changes brought in with the recently issued EurOtop II manual; a detailed worked example is given of the calculation of extreme wave conditions for design; additional examples have been included on the reliability of structures and probabilistic design; the method for tidal analysis and calculation of amplitudes and phases of harmonic constituents from water level time series has been introduced in a new appendix together with a worked example of harmonic analysis; and a real-life example is included of a design adapting to climate change. This book is especially useful as an information source for undergraduates and engineering MSc students specializing in coastal engineering and management. Readers require a good grounding in basic fluid mechanics or engineering hydraulics, and some familiarity with elementary statistical concepts.
A highly readable book on the nature of beaches, including thedynamics of the shoreface, surf, swash and backbeach, and globallyat the regional variations in beach systems from the tropics to thepoles. The beach and adjacent shoreface are the most dynamic part of theEarth's surface. They represent a narrow zone where waves, tidesand winds continously interact, producing, wherever sediment isavailable, hundreds of thousands of kilometres of beach systems.Beaches are also the focus of intense pressure from users anddevelopers, and for these reasons alone a knowledge of beachsystems and their morphodynamics is critical to their sustainablemanagement. This book is the first to: * provide an in-depth and holistic view of beach systems, lookingboth in detail at the different beach zones and globally at rangeof parameters influencing regional variation * examine the relationship between beaches and ancillary dunesystems and includes chapters on beach ecology, safety,stratification and barrier evolution. The book is designed for use in the classroom and the office, beingaimed at university level students and coastal professioanls.
