It explores the complex relationship between groundwater management and environmental integrity, delving into topics like the impacts of groundwater extraction on ecosystems, the role of groundwater in climate change adaptation and mitigation, and the effects of surface water-groundwater exchange on groundwater quality.

This book provides a comprehensive understanding of the water resources status in the northern areas of the Qinling Mountains, China, which are considered strategically important as the central water tower of China. The book presents the findings of a thorough water resources research conducted in the northern Qinling Mountainous areas from 2019 to 2022. The research included field investigations of the main rivers and groundwater in the region, estimation of base flow for the main rivers, and assessment of water quality for both rivers and groundwater. Special attention was given to studying surface water-groundwater interactions in selected areas of the northern Qinling Mountains. Furthermore, the book thoroughly examined the land use changes and their impacts on groundwater nitrate pollution in selected areas. The evaluation of health risks associated with nitrate pollution was discussed, and measures for water resources protection and management in the northern Qinling Mountainswere proposed. This book will be a valuable resource for water professionals and practitioners seeking new knowledge about water resources in this rarely reported area of China. It will also provide meaningful insights for decision-makers involved in formulating effective water policies.

This book examines the Sulige Gas Field—China’s largest natural gas field—as a case study. Drawing on field hydraulic fracturing data and laboratory water–rock interaction experiments, it systematically investigates the geochemical processes occurring during hydraulic fracturing. These processes are analyzed using X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), geochemical modeling, end-member mixing analysis, and isotopic tracing.In addition, the book explores regional water environmental issues triggered by hydraulic fracturing, as well as strategies for managing and utilizing flowback water resources. The findings provide a theoretical foundation and technical support for the green and sustainable development of unconventional energy resources, while significantly advancing the understanding of geochemistry in deep subsurface environments.By bridging fundamental geochemistry and practical engineering, this book offers actionable insights for reservoir engineers, geochemists, and policymakers to address environmental and engineering challenges effectively.

This book serves as a vital resource for researchers, practitioners, and policymakers, addressing the complex challenges posed by climate change, population growth, and environmental degradation. Recent Advances in Water Science is a comprehensive volume that captures the latest developments and innovations in the field of water science. It integrates a wide range of topics, from fundamental hydrological principles to cutting-edge technologies, emphasizing the need for holistic and sustainable water management.This book is organized into several key sections, each addressing critical aspects of water science. It begins with an exploration of the water cycle and hydrological processes, providing essential context for understanding the dynamics of water systems. This foundation is followed by an in-depth look at urban wetlands which are important in water purification, flood mitigation, groundwater recharge, climate regulation, carbon sequestration, and biodiversity support.A significant portion of this book is dedicated to water quality management, addressing pollution control, water treatment, and the impact of emerging contaminants on human health and ecosystems. The importance of sustainable practices and adaptive management strategies is highlighted, especially in the face of changing environmental conditions. This book also examines integrated water resource management (IWRM), emphasizing the need for collaboration and stakeholder engagement to balance competing demands for water.Throughout this book, contributions from leading experts provide insights into current research and future directions. These chapters cover topics such as climate change impacts, application of artificial intelligence in water science, and emerging contaminants. This book also explores the role of policy and governance in shaping sustainable water management practices.
