“…On the other hand, topographical maps (Survey of India) and satellite images (Landsat) were taken from various years, also were employed to determine the changing pattern of morphology and unstable character of the investigated river over time. Remote Sensing and GIS aid in the identification of changes in landscapes, particularly in terms of spatio-temporal scale (Dutta and Das, 2020;Das and Saha, 2022), and these techniques reduce the usage of traditional human methods and equipment while also saving time. In this research, we have used geospatial technologies to evaluate the effects of bank erosion in a specific location.…”

“…The dynamics of channel migration patterns, the relationships between variables, and the extension of the observation around the center value have been analyzed with the help of descriptive statistics. For this purpose, mean, Standard Deviation (SD), Coefficient of Variation (CV), skewness and kurtosis were used to explain the finding (Das and Saha, 2022;Mandal et al, 2018;Das, 2017;Dey and Mandal, 2019).…”

The power of the river does not always work to the benefit of living things; rather, it has the ability to destroy human society and has negative effects on the environment. River Teesta has a prodigious significance on the riverine dweller and its changing precarious behavior has repercussions on the lives of millions. Utilizing satellite images and 41 years of temporal analysis, the mapping of channel extraction and channel shifting has been demonstrated. Delineating the exact channel boundary is a laborious operation, but MNDWI technique is really valuable in this situation to produce valuable results. Descriptive statistics are used to analyze the Teesta River's active flow line migration trend and channel migration behavior. A particular river's oscillating character over time has both beneficial and detrimental power, destroying important resources for environmental sustainability and human society while also providing fertile mother earth as a source of wealth. As a result, another goal of the current study was to determine how vulnerable riverine residents were. A Livelihood Vulnerability Index (LVI) based on the riverine inhab-itants' exposure, sensitivity, and capacity for adaptation was created. According to the findings, the river's erratic behavior is putting the people who live beside it in danger. Therefore, it is vitally necessary to implement a capable management strategy to stop bank failure at the Teesta-Dharala confluence in order to save the riverine residents.
