Hydro-Geomorphic Dynamics And Anthropogenic Alterations Of The Yamuna River Channel In The Indo-Gangetic Plains

Author(s): Soukatara Begum

Abstract

Rivers are highly dynamic geomorphic systems that constantly adjust their morphology in response to variations in discharge, sediment load, climatic conditions, and tectonic settings. In recent decades, however, anthropogenic interventions have emerged as dominant forces influencing river behavior, particularly in densely populated alluvial plains. The Yamuna River, one of the principal tributaries of the Ganga, flows through the Indo-Gangetic Plains—one of the most intensively utilized and densely inhabited regions in the world. This study presents a comprehensive analysis of the fluvial dynamics and anthropogenic impacts on the channel morphology of the Yamuna River using geospatial techniques. The research integrates multi-temporal satellite imagery, GIS-based morphometric analysis, and secondary data sources to assess changes in channel width, bankline migration, sinuosity, braiding intensity, and sediment dynamics over time. The study underscores the growing dominance of anthropogenic controls over natural fluvial processes, leading to altered geomorphic equilibrium and ecological degradation. It highlights the need for integrated river basin management, restoration of environmental flows, and sustainable land-use planning to ensure the long-term health and resilience of the Yamuna River system.
