Abstract
The
present study is done to understand the frequent change in the platform
dynamics of river Ganga from Mirzapur to Ballia in Uttar Pradesh. The study is
based on sequential river platform maps generated from the time series multispectral
datasets, which revealed a periodic pattern of evolution of the river system
over the study area. The study depends upon using Landsat sensors that are
Trade Marks (TM), Market Stabilization Scheme (MSS), and Enhanced Thematic
Mapper (ETM+) acquired through the years 1975 to 2015. The present work deals
with Meandering index and Braiding index, which determines the sinuosity,
tortuosity, and braiding of the river Ganga to investigate and classify the
river into straight, sinuous, and meander category. The study reveals that the
sinuosity was increased from 1.38 to 1.56 from 1975 to 2015, whereas the
braiding index is observed as 0.6 to 0.26 at one of the Reaches within the
study area from 1975 to 2015, which reveals that the river is exhibiting braiding
as well as meandering pattern. The study reveals that the platform of river
Ganga is shifting continuously, and the factors behind the shifting of river
course are natural as well as anthropogenic.
