Spatial Modeling of Environmental Pollution and Ecological Risk provides valuable information and insights for researchers, students and professionals in geography, hydrology, sedimentology, soil science, agriculture, engineering and GIS as they face increasingly complex challenges around development strategies for a sustainable society. Written by the world's leading researchers in their field, each article will begin with a short introductory essay that includes an overview of the sections' papers.

Individual chapters focus on the core themes of research and knowledge and some topics that have received lesser attention. Each chapter will review the current understanding of knowledge regarding the present study and scope and consider where future efforts should be directed.

The Bhagirathi-Hooghly Basin in India is one of the most densely populated regions in the world and is undergoing rapid transformation of its natural landscape induced by human interventions, such as mushrooming of dams and barrages, deforestation, and urbanization. Human activities and interventions on basin landforms and the processes that shape those landforms have accelerated at an alarming rate. This book uses spatio-temporal analysis to understand the major anthropogenic signatures on land use and land cover changes and the impact these activities have on the landforms and processes of the Bhagirathi-Hooghly River and its sub-basins. It answers the what, where, why, and how of the anthropogenic signatures involved. Recent case studies on the impact of anthropogenic signatures on fluvial forms and processes make this book a useful resource for students and researchers in the earth sciences, local governments, urban planners, and all concerned with rural developments.

Tropical deltas of the world are in decline and are threatened by climate change, geo-environmental dynamics, natural hazards, and disasters. This book is a comprehensive discussion of the present delta crisis and the various risks the deltas are facing due to human and natural factors. It addresses their resilience, the importance of biodiversity, and the future adaptations for sustainable management of tropical deltas. The use of geospatial tools for the assessment and modeling of environmental degradations and the applications of artificial intelligence (AI) and machine learning (ML) are examined in 22 chapters, from different major deltas of the world, to help readers understand the interdisciplinary perspective of deltas’ vulnerability and sustainability.

Features

This reference book is for researchers, academics, graduate and senior undergraduate students in geography, geomorphology, hydrology, regional planning, environmental science, ecology, and engineering, and those interested in water conservation and sustainability, including professionals in industry and government, and human rights activists.

This volume provides a versatile introduction to the study of drainage basin evolution, morphology, drainage basin hydrology and sedimentology, human interference, natural and anthropogenic hazards and various management techniques. 

This book offers the responsible factors of sediment yield and their absolute and specific growth and rate of delivery through tributaries to the main streams. Rivers are important geomorphic agents which reflect an amazing variety of form and behaviour, showing the wide range of natural environment in which they are originated.  The drainage system evolution and spatial network development within the dynamic nature are being discussed and how they are adjusted in the geomorphic time scale over the millions of years. This book shows how drainage systems function and react to change and why this thoughtful is required for flourishing integrated basin management. In tropical and sub-tropical countries population pressures as well as different developmental projects are being executed on the drainage basin without proper planning. Today scientists consider drainage basin as an administrative unit during implementation of regional projects. In this context this book will carry a bench mark for scholars and young scientists.

This book focuses on neotectonic movements and river channel evolution of the Indian subcontinent, with special reference to the Himalayan Neotectonics. Neotectonic movements have played an important role in channel evolution in tectonically active zones especially for the mountain chains, foredeeps and active deltas. The book addresses the issues of the channel evolution in neotectonically active domains of India. It aims at readers of India as well as abroad, interested in earth sciences, geomorphology, tectonics, physical geography and river forms and processes of India. 

This book addresses the various factors affecting fluvial systems, the processes governing them, system responses arising from human-nature interventions, and geospatial and geo-ecological modeling to understand system behaviour better and restore degraded ecosystems around the globe. Thanks to their hydrological and agro-ecological advantages, humans have settled along riverbanks since the dawn of civilization. Thus, the ancient "ecumene" (settlements) were located near major rivers worldwide. This legacy of river-based civilizations continues to this day in many forms. However, in the course of the ''Anthropocene'' era, countless fluvial systems have been altered by human interventions in the form of large-scale dams and barrages, changes in land use and land cover, road-stream crossings, mining of sand and gravel, mushrooming of brickfield, expansion of modern agriculture, industrial growth, and urbanization. Thus, the present-day development pattern threatens fluvial systems,especially riverine morphology and ecosystems. In brief, human-induced morphological changes, water pollution, eutrophication, and related damages to aquatic organisms are the major threats to fluvial systems. Thus, maintaining the ''environmental flow'' of the world''s major rivers to preserve the proper functioning of riverine ecosystems and promote sustainable development is a global challenge.

This volume covers the floods of the major rivers of the Ganga-Brahmaputra-Meghna (GBM) Delta, and storm surge related coastal floods in these regions. The book is dedicated to addressing floods from an integrated physical-social perspective to provide students and researchers with a holistic understanding of floods in terms of both human and geomorphological aspects. The systematic coverage of all the major rivers and coastal areas in the GBM delta and surrounding regions will foster a clear comprehension of this dense reservoir of population, where thousands of people are impacted every year due to flood hazards and agricultural destabilization. This comprehensive treatment of flood issues in the region covers flash floods, fluvial floods, fluvio-tidal floods, and coastal floods, and outlines flood management strategies to maintain ecological integrity and environmental stability, and prevent harmful impacts of future floods. The book is intended for students and researchers in earth and environmental sciences, especially geomorphology, hydrology, geography, geology, natural resources management, and regional planning.

This book discusses the issue of riverbank erosion and its associated causes, risks and social challenges in the Bengal Delta. The book covers the physical processes and indicators of riverbank erosion such as sediment flux and channel morphology, the anthropogenic and natural causes of erosion, the social consequences that afflict vulnerable communities who depend on the delta for their livelihoods, and potential solutions to harmful erosion processes such as bioengineering methods and increased community governance through a socio-hydrological approach. Though the Bengal Delta is one of the most populated regions in the world, few publications exist that discuss riverbank erosion as a major threat to environmental and livelihood sustainability in a comprehensive manner. The book will fill this gap in research for students and researchers in geography and environmental sciences, and will engage regional planners, decision makers and policy makers to further their understanding of the complex social and environmental aspects of the Bengal Delta associated with persistent and worsening riverbank erosion.
