Epistemological Assessment of the Spit Morphodynamics of Junput Beach, Kanthi Coast, India

Author(s)

Abstract:

A spit is a narrow and elongated coastal landform, usually made up of sand, extending outwards and exposed to the sea. It is a depositional landform that is formed under the influence of longshore currents. Coastal features of Junput beach have experienced exceptional seasonal transformation due to wind direction, speed, and wave energy variation. The main objective of the study is to trace the morphodynamic changes of the spit under the monsoonal wind system and other phenomena, additionally focusing on the longshore sediment transport variation. For this research, primary data have been used, collected from ground surveys at Mankaraiput, Saradpur, and Baguran Jalpai stations, while secondary data, Landsat satellite image from USGS and digital shoreline analysis system (DSAS) tool have been used to understand the morphometric changes on Junput spit for a few decades. The results of this study show that during the monsoon and post-monsoon seasons, sedimentation is more due to the influence of NE winds, but the stronger SW winds transport less sediment. Thus, erosion and redistribution of sediment and the associated morphological changes of the spit are easily understood.
