This book explores the application of the open-source software OpenGeoSys (OGS) for hydrological numerical simulations concerning conservative and reactive transport modeling. It provides general information on the hydrological and groundwater flow modeling of a real case study and step-by-step model set-up with OGS, while also highlighting related components such as the OGS Data Explorer. The material is based on unpublished manuals and the results of a collaborative project between China and Germany (SUSTAIN H2O). Though the book is primarily intended for graduate students and applied scientists who deal with hydrological modeling, it also offers a valuable source of information for professional geoscientists wishing to expand their knowledge of the numerical modeling of hydrological processes including nitrate reactive transport modeling. This book is the second in a series that showcases further applications of computational modeling in hydrological science.

This book focuses on the treatment anddisposal technology used for solid waste in China, puts forward an optimalmanagement scheme that takes into account the complete lifecycle, andintroduces a new technical model that reflects the synergies of resourceutilization and secondary pollution control. In addition, it provides a set ofmethods for professional on-site investigation, risk assessment, classificationmanagement and control to minimize the risk of groundwater contamination bysolid waste at landfill. Given the extent and depth of knowledge and experiencegathered in the book, it offers an important reference guide for governmentmanagers, environmental researchers, and all those involved in and concernedabout solid waste disposal.

This book argues that groundwater pollution risk assessment is the essential foundation of groundwater pollution prevention and control. It is on this basis that economic leverage is used to make new breakthroughs in groundwater protection and governance. Presenting a case study on the Jilin Section of the Songhua River, the book applies the overlay index method to assess the shallow groundwater pollution risk and identify high-risk areas and major pollution sources in an effort to identify the mechanism of interaction between industrial structures and groundwater pollution. Further, it proposes concrete measures for preventing and controlling groundwater pollution from an industrial economics perspective. As such, the book offers a valuable resource for all graduate students, lecturers and researchers who are interested in learning about resources and environmental economics.

This book systematically introduces the key technologies for differentiated resourceful utilization of rural organic wastes based on high-efficiency anaerobic fermentation and bio-augmented composting, and discusses differentiating sources of organic wastes, integrating recycling technologies, developing key equipment, and researching management mechanisms. In addition, it describes the development of viable techniques and low-pollution, low-cost, and low-maintenance equipment. It also includes the technical specifications for the differentiated resourceful utilization of rural organic wastes and presents the energy-fertilizer integrated resourceful utilization method for rural organic wastes. Providing technological insights into improving the resourceful utilization level of rural organic wastes, this book is a valuable reference resource for administrative staff, researchers in the field of environmental protection, and technicians in enterprises involved in the treatment and disposal of solid wastes.

This book introduces readers to environmental background investigation, pollution source intensity evaluation and risk assessment approaches used at three main types of groundwater-contaminated sites: municipal domestic waste landfills, hazardous waste landfills and oil-contaminated sites. In addition, typical contaminated sites throughout China are examined to demonstrate how these approaches can be applied for their investigation, assessment and restoration. By reading this book, readers will gain a deeper understanding of the restoration and management of typical groundwater-contaminated sites.
