Schlagwort(e): Earth sciences ; Chemoinformatics ; Geology Statistical methods ; Hydrogeology ; Computer simulation ; Environmental chemistry ; Earth Sciences

Beschreibung / Inhaltsverzeichnis: 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 The material is based on unpublished manuals and the results of a collaborative project between China and Germany (SUSTAIN H2O).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

Beschreibung / Inhaltsverzeichnis: This volume addresses latest results of the Major Water Program of the Chinese Government which aims at the restoration of polluted water environments and sustainable management of water resources in China. It specifically summarizes the results of the BMBF-CLIENT project “Management of Water Resources in Urban Catchments” and the related MoST project “Key Technologies and Management Modes for the Water Environmental Rehabilitation of a Lake City from the Catchment Viewpoint” in Chaohu. The project is conducted by the Helmholtz-Centre for Environmental Research UFZ, Technische Universität Dresden, German and Chinese companies (WISUTEC, AMC, bbe Moldaenke, itwh, OpenGeoSys e.V., HC System and EWaters) in close cooperation with Tongji University, Nanjing Institute of Geography and Limnology of Academy of Sciences, Institute for Hydrobiology of the Chinese Academy of Sciences and the Chaohu Lake Management Authority. The book explains the development of concepts and solutions for sustained water quality improvement in Chaohu, combining urban water resource management, decentralized sanitation solutions, methods in water quality assurance, environmental information systems and groundwater modeling
