Modeling the fate of chemical constituents such as cations and anions, organic and inorganic ligands, etc., is essential to understand the long-term utility of groundwater for various purposes. The chemical modeling helps to describe the chemical characteristic of an aqueous system to solve a simultaneous set of equations, which explains the equilibrium reactions and mass balance on dissolved element for the output consists of theoretical distribution of aqueous species for dissolved elements. The book in total includes ten papers dealing with the instrumentation techniques for the analysis of various major, minor ions and trace elements and focuses on the geochemical modeling to get a prime idea about the different concepts adopted in modeling and the evolution of different geochemical models. The chapters cover the speciation of different ions, case studies by using inverse and forward modeling in different Indian scenarios, application of GIS and biogeochemical modeling to get a comprehensive overview of the applications of the geochemical models in water research.
This book describes essential principles of and approaches to monitoring and modeling algal blooms. Freshwater algal blooms have become a growing concern worldwide. They are caused by a high level of cyanobacteria, particularly Microcystis spp. and Cylindrospermopsis raciborskii, which can produce microcystin and cylindrospermopsin, respectively. Since long-term exposure to these cyanotoxins may affect public health, the reliable detection and quantification of these harmful algae species has become a priority in water quality management. The book utilizes an advanced monitoring approach to identify and quantify cyanobacteria species and various cyanotoxin-producing genotypes. Further, it uses a modeling approach to forecast the occurrence of the phytoplankton that causes algal blooms in freshwater reservoirs, providing a comprehensive picture of currently available micro- and macro-techniques for studying the problem of algal blooms. As such, it offers a valuable guide for researchers, graduate students and professional engineers engaged in monitoring and modeling water quality in lakes and reservoirs. Dr. InChio Lou is an Assistant Professor at University of Macau, Macau, China. Dr. Boping Han is a professor at Jinan Universtiy, Guangzhou, China. Weiying Zhang is a researcher of Environmental Engineering in the area of freshwater phytoplankton at University of Macau, Macau, China.
The chapters in this book present state-of-the-art geomatics technologies applied in global environmental studies. This text provides the latest research findings and delivers complete references to related publications. This book will motivate the undergraduate and graduate students, researchers and practitioners to better understand the environmental changes with informed solutions.
Global Change studies are increasingly considered a vital source of information to understand the Earth Environment, especially in the framework of human-induced, climate change and land use transformation. Satellite Earth Observing systems and geomatics technologies provide a unique tool to monitor and model the changes, respectively. While the range of applications and innovative techniques are always increasing, this book provides a summary of key study cases where satellite data offers critical information to understand the usefulness of the geomatics technologies and global environmental issues. Geomatics technologies provide powerful tools to model and analyze the effects of those global environmental changes towards minimizing their adverse impacts on human health and the environment.
