Book Description

This book explores fluvial processes and their consequences on river dynamics in India. It discusses the integration of geomorphic, hydrologic, and socio-economic data with various policies and decisions regarding sustainable river basin management. The volume looks at the origin and development of streams, chronology of fluvial geomorphology, fluvial system concept, process–form interaction, river dynamics, channel migration, flow regime, channel types, and hydraulic and morphometric parameters; and explains how changing hydro-geomorphological dynamics have influenced land use patterns, nature of fluids, behaviour of floods, etc. It examines channel migration vulnerability and bank erosion hazard vulnerability of the Torsa River in the eastern region of India as a case study using channel migration zone and Bank Erosion Hazard Index models. The book presents a new research framework based on field surveys, scientific investigations, and analytical techniques and methods to interpret key geoinformatics data.

With its extensive illustrations, this book will be useful to students, teachers, and researchers of geography, earth sciences, environmental geology, and environment and disaster management. It will also interest geographers, civil engineers, hydrologists, geomorphologists, planners, and other individuals and organizations working on fluvial processes and riverbank erosion problems globally.
