Abstract
This study seeks to examine the detection of course change in one of the major rivers of India, that is the Ganga, between the period of 1980 to 2020 and utilizes satellite driven data to demonstrate the visibility of shifting in its course. The purpose of study area is to find out the change detection of the river course. The channel shifting of the river course has been used to demonstrate the historical change in Landsat MSS, TM, ETM, and OLI/TIRS satellite images in the decades of 1980, 1990, 2000, 2010 and 2020. The study exhibits several reasons responsible for and lead to this shift, such as erosion problems and changing characteristics of the Ganga from Rampurghat to Chunar at different cross-section site points. This research area has been divided into six cross-sections, namely, XS-1, XS-2, XS-3, XS-4, XS-5, and XS-6. We attempt to examine how the river’s shape and position have witnessed a change during the 1980–2020 period via using remote sensing and GIS methods. We have identified that the course line of the Ganga has demonstrate a shift via using five types of satellite imagery in the above-mentioned period. The process of channel shifting has included an erosional and a depositional development occurred due to infrastructure damage by sedimentation, flood and changing river course. The Ganga course has shifted towards the south and the north direction places which as a result leads to village erosion. The major aspects of this study have a direct interaction with the physical and socio-cultural environment from upstream to downstream in cross-section. The course change detection of the study has been taken in the context of the river management and planning for future prevention of agricultural land, kuccha houses, food, and economic loss to farmers.
Highlights
The Ganga is popularly known as the holy river
The Channel Migration Zone (CMZ) is a river channel is referred. The Ganga river basin is described by change detection of the study region on historical periods, before the situation goes into the Bay of Bengal
It is revealed that the study region of the maximum channel was increased the width river in 2020, the Landsat satellite imagery
Summary
The Ganga is popularly known as the holy river It is the second largest river in the Indian subcontinent covers several states in India. The Ganga valley covers the major part of Uttar Pradesh. Pollution, and sediment and study elements channel morphology is a major problem in the present time and is very important for this region. The detection of change in the river course is a study that is reinforced by the application of the RS, and the GIS methods. These two methods, Remote sensing and GIS are broadly used for the detection and monitoring of fluctuations in the physical environment. We will utilize the RS and the GIS techniques to detect the changes in the Ganga course near Mirzapur city, India
