The edited book deals with climate change and its response to river system which is one of the most burning issues of the Global environment. Due to urbanization and industrialization land degradation and resource depletion are happening and promoting livelihood challenges in the world which is reflected in the book too. The book addresses the construction of dams over large rivers and its possible consequences in the environment. Changes of the hydrology and sedimentology are to be addressed in the book. The climate change phenomena and associated geomorphic hazards and contemporary environmental issues such as sea level rise, coastal flood, drought, wind erosion, flood, soil erosion, landslide, depletion of ground water, coastal erosion etc. are elaborated in the book with suitable methods and techniques. So this edited book will contribute a lot to general to particular filed of studies and will help to geographers, geomorphologists, environmentalists, planners, policy makers and developers for studies and promoting regional plans and development.

This book presents select proceedings of North-East Research Conclave (NERC 2022) that will help pave way toward disaster risk reduction through a holistic and multidisciplinary approach. The book discusses topics, such as rapid pace of climate change, its deleterious effects on nature and natural systems, human interventions in altering the natural geographical and geological systems, widespread urbanization, recurrent unwarranted rainfall and cloud bursts, unprecedented flooding, catastrophic landslides, dam breakages, glacial outbursts, snow avalanches, seismicity and its impacts, liquefaction, and wreaking environmental pollution leading to unimaginable toll on lives, property and economy. The book also discusses approaches to address such issues and frame a refined path towards a sustainable future, such as a three-fold approach like ¿ Awareness, Inferences and Implementations. For this approach, it is ardently necessary to understand the core reasoning behind the disasters, theirimpact on the socio-economic contexts, and the ways to mitigate them. The book can be a valuable reference for beginners, researchers, and professionals interested in disaster risk reduction and allied fields.

This book introduces shield construction risks under mixed face ground condition, analyzes the shield tunneling risks, gives definitions of relevant risks and creates the theoretical system of shield tunneling technology under mixed face ground condition, that is,  geology is the foundation, TBM is the key, and people (management) is the essence. The content provides numbers of targeted solutions, such as dual-mode TBM, multi-mode TBM, millisecond delay blasting for boulders, Paste HDN, auxiliary pressure balance tunneling and so on. This book can make researchers who engaged in shield tunneling to get experiences and lessons from it, so as to make the right decision during shield type selection, standardize shield tunneling, take proper action, avoid or reduce construction risks, and minimize casualties and property losses.
