The most pertinent tsunami related issues such as water borne debris during tsunami flooding, design loads to incorporate for impact forces on coastal zone infrastructure, detection and warning are meticulously incorporated in this book.Modelling of various coastal processes have proven to be successful in the recent past, which includes extreme events such as storm surge, cyclone, etc. The possible provisions for computational/numerical tsunami modelling and real physical modelling in laboratory are elaborated. The propagation, evolution and run-up of tsunami waves and their associated non-linear dynamics are discussed.The significant inferences from the experts who have had hands-on experience working with the extensive magnitude of a tsunami disaster reported on the signature studies and post-facto effects of the 2004 Indian Ocean Tsunami, with respect to the damages along the Indian coast.

Coastlines, like many things around us, are constantly evolving. Keeping pace with the changes and their development is necessary to ensure their stability and to maintain eco-equilibrium for nearshore hydrodynamics and morphodynamics. Supported with field measurements for model validation, several numerical and analytical tools are available to us to understand the physical processes in the vicinity of these water bodies.This book encompasses the engineering principles involved in field data observation, measurement, collection, and processing; the prediction of wave climate and sediment transport using measured field data; numerical modelling involving calibration and validation of the hydrodynamic and morphodynamic processes; and the study of the underlying physical processes and the application of sustainable engineering measures to combat coast- and estuary-related problems.The book has three sections: The first section is an elaboration on the need for and framework of the existing management and engineering notions. The second section details the measurement of the various parameters such as wave climate (offshore and nearshore), shoreline changes, beach profile variation, and sediment transport rates. The third section describes the aspects of wave prediction to arrive at design characteristics and modelling of the hydrodynamic and morphodynamic processes along open coasts and tidal inlets.This book is designed to benefit students pursuing coastal engineering as their field of specialization. It could also serve as a guidebook to engineers, planners, and decision makers working in the fields of coastal, estuarine, and harbour engineering, governmental and private agencies that plan the financial outlay for coastal development projects, and private consultants dealing with maritime hydraulics.

This unique compendium comprehensively covers several important topics related to the field of maritime hydraulics, particularly the underlying physics in the wave structure interaction with the coastal structures, coastal and inland flooding during extreme events in addition to perineal erosion. These topics are well understood through physical and numerical modelling, in which the scale effects, proving the models and its range of applicability are vividly discussed.This useful reference text serves as a guide to engineers, planners, researchers, decision makers and graduate students working in the field of coastal, estuarine and harbor engineering.

This book can potentially serve as a comprehensive textbook for students pursuing this subject either as degree or an elective course. It covers all the fundamental physics behind the different phenomena taking place in the near shore regions and the coast as well as the various methods to estimate its impact. Basic knowledge of water wave mechanics is crucial in understanding the coastal processes taking place in the near shore. The assessment of incident forces due to wind, wave, tide, current etc. is important to evaluate the resultant impact they cause on the shoreline and structures.This book emphasizes the importance of sediment dynamics by analyzing the sediment characteristics, the physics of its motion and movement, factors responsible for the fate of sediments etc. It also highlights the erosion problem which is most prevalent across the sandy coasts, additionally erosion combating methods and techniques are also described with real time field problems and their solutions.A wide range of coastal structures and their design principles are included in this book in order to give the reader a holistic understanding to the readers. This book also includes the design challenges and introduces the reliable modeling tools and techniques, which is very useful for beginners working in this discipline.

The book ‘Climate change impacts and adaptation strategies for coastal infrastructure, water resources, and waste management along the coasts’ offers a critical exploration of the profound challenges that climate change poses to Indian coastline districts. It focuses on reducing uncertainties in predicting coastal dynamics due to climate change impacts, specifically along India’s coastlines.Organized into nine individual chapters, this book covers key topics such as wave prediction with a deep understanding of wave dynamics, inundation due to storm surge and rainfall, climate change and coastal hazard vulnerability assessments, and adaptation strategies to reduce uncertainties for the existing coastal defense systems in an urban environment. The initial chapters focus on improving the efficiency of predictive models to address knowledge gaps, gradually moving to practical solutions such as promoting soft measures and enhancing local community engagement in adaptation planning. The book highlights key findings, including added uncertainty in water availability, increased vulnerability due to overlooked socio-economic systems, the rigidity of urban infrastructure (like wastewater systems), and heightened risk from delayed cyclone landfalls. In addition to addressing these gaps, this book also explores options such as soft, nature-based solutions and decentralized urban systems in densely populated and highly vulnerable populations in the local context. By highlighting critical knowledge gaps, the volume offers comprehensive, research-backed approaches to effectively address uncertainty. Readers will gain the technical foundation for strategic coastal adaptation, resilient planning, and proactive disaster management, enabling them to implement low-impact, efficient solutions that secure the future of our coastal regions.
