Identification of Fluvio-Geomorphological Changes and Bank Line Shifting of River Bhagirathi-Hugli Using Remote Sensing Technique in and Around of Mayapur Nabadwip Area, West Bengal

Sarmistha Mallick

Abstract: The present study focuses on the deltaic region of west Bengal, which is one of the most dynamic natural regions of the state. The study area is a part of moribund deltaic region of district Nadia. Bank erosion, channel shifting, siltation of channels, decaying of oxbow lakes are common geomorphic hazards in Bhagirathi- Jalangi interfluve and further south of both of the flood plain of Hugli. The main focus of the study area is to identify the different pattern of fluvio geomorphic features on the flood plain. For the analysis the data on river planform are collected from the survey of India toposheets and a number of satellite imageries. Surveys were carried out to compare the present scenario and the past situation. The analysis reveals that the fluvio geomorphological changes over the period of 45 years are considerably significant. Anthropogenic causes have a greater influence to change the morphology and increases the rate of bank erosion.
