Spatiotemporal Detection and Monitoring of Beas River Bank Erosion Using GIS Analytics, Punjab, India

Fluvial geomorphologyFluvial geomorphology showsGeographic Information System (GIS) the dynamic nature of rivers that result in changes in the size and shape of the river caused by erosion and accretionAccretion. The present chapter is related to the ‘River Beas’ in PunjabPunjab, India, sharing a border between two districts Tarn Taran and Kapurthala. This study shows the spatiotemporal variations in river bank lines due to erosion and accretionAccretion within ten years, i.e., 2013–2023. GeospatialGeospatial techniquesGeospatial techniques have been proven more accurate and reliable for quantitative analysis and mapping. The river bank erosionBank erosion is monitored using Google Earth imagesGoogle Earth Image at different times, i.e., 2013, 2018, and 2023. To examine the erosion and accretionAccretion of river banks, changes to the river bank line, and variations in river widthRiver width, Google Earth imagesGoogle Earth Image were processed and geo-referenced with WGS 1984. The superimpose technique is performed using ArcMap 10.8 software to highlight the relative change in bank lines from 2013–2018–2023. The analysis showed the river bank line changes due to erosion and accretionAccretion. The river’s width gradually widened from both sides of the bank. The river widened the course and eroded the right bank, creating a convex path. The river’s width gradually widened from both sides of the bank. The changes in the river in the earlier five years were more than in the recent five years. The resulting information will be helpful for the planning and development of this area. Many strategies and plans can be applied using this chapter’s findings on river bank erosionBank erosion.
