This volume reviews recent hydrological and environmental issues resulting from human-induced water pollution practices while providing case studies on the physical, chemical, and eco-biological techniques used to mitigate the impacts of river ecosystem pollution in South Asian countries. The book demonstrates the key methods of measurement, monitoring, mapping, and modeling of river water quality and how it is impacted by pollution and incorporates contemporary geospatial technological applications for the management and sustainability of future water resources. The major topics that the book addresses are the fundamental concepts of river ecosystem health, riverine ecology and habitats, risk assessment of riverine pollution, and technology-based river pollution control strategies. The book will serve as an interdisciplinary guide for researchers, students, and GIS specialists working in various disciplines, including pollution hazards, river ecosystem restoration, water quality, remote sensing, zoology, natural resources management, and environmental geography.
