Morphological Dynamic of Ekakula Spit and Kalam Island in Kendrapara District of Odisha—A Geospatial Approach

Abstract

Odisha Coast of India is about 480 km long stretching and oriented in a SW-NE direction. The sediment contributions from the rivers are deposited along the coast. The littoral drift deposition builds spits and bars at the river mouths especially at the southern side of the river mouths. The one of the study area is situated between 20°40’57.417”N and 20°45’49.947”N latitude and 87°1’5.576” E and 87°7’4.959”E longitude. Another is the Dr. Abdul Kalam Island, formerly known as Wheeler Island, an island off the coast. The Integrated Test Range missile testing facility is located on the island. In May 2013, increasing concern has been drawn to the change of the island's topography, owing to sand erosion. Since the island is technically a shoal, seawater frequently causes sand-shifting. The situation is being monitored by geological experts from National Institute of Ocean Technology and the DRDO. The study has taken through Remote Sensing and GIS technology with time series satellite imageries during the year 1973 and 2017. The spit has growing gradually but now the erosion process has increased the spit length during the year 2015 and 2017. During the year 2009 and 2017, the Kalam island has stable and some areas are deposited.
