Morphological Changes and Their Environmental Impacts in the Behula River System

Abstract The changing interactions between the hydrological process, the sediment load, the geology, and the anthropogenic interventions are included in the river morphology. The Behula River, a major distributary system of lower DamodarBhagirathi system in West Bengal, is known to have undergone great morphological changes over the last decades. The changes have had consequences on the channel pattern, bank stability, sediment dynamics, and floodplain environments, hence exerting considerable environmental impacts on riparian ecosystems and human settlements. The given work is devoted to the morphological changes study in the Behula River system and the analysis of its influence on the environment through the synthesis of the geomorphic principles, the evolution of the drainage system, and the comparative analysis of the fluvial systems. The paper relies on recorded works of fluvial morphology, anthropogenic variations, and channel planform dynamics to India and other analogous river systems worldwide to recognize the role of the flow regulation, feeder canals, land-use change, and redistribution of the sediments in changing the river channel. Based on the results, the increasingly narrowing of channels, banks' erosion, loss of natural drainage connection, and the deterioration of the floodplain contributed to the enhancement of stresses on the Behula basin environment. The paper puts emphasis on the need to have combined river basin management which identifies geomorphic sensitivity and in the ecological dimension sustainability.
