A Study on Dynamics of Krishna River Mouth, East Coast of India: A Geospatial Approach

Abstract

Because of the strategic location Krishna River mouth, research on the dynamics of the river mouth is crucial. The data were created by combining multi-temporal satellite images from IRS P6, LISS III, and Landsat 8 over an 8-year period, namely, 2009, 2012, 2013, 2014, 2015, 2016, 2017, and 2018. Change detection investigations on the river mouth width on its southern tip were regularly and eventually monitored. It has been discovered that the river mouth is rather dynamic. It is fluctuating on a regular and consistent basis. Obviously, there is a threat to the estuary. The river mouth is critical to mitigating, managing, monitoring, and protecting the existing width in order to keep the river biologically, ecologically, and economically vibrant and active. This work discovered a significant alteration in the river mouth as inferred by using geospatial tools such as Remote Sensing and GIS.
