Geomorphological Dynamic of Mangala Cut of Puri District, Odisha: A Geospatial Approach

Abstract

Odisha rivers are east flowing and the Mahanadi is the largest river in Odisha. The river Bhargavi is the southern branch river of Mahanadi, which flows to Chilika lagoon parallel with Bay of Bengal. In the year 1929, the toposheet has no information about Mangala cut. In the year 1937, it was made for controlling flood in Bhargavi river. The Mangala cut was constructed to get relief from the regular flood submergence of Puri Sadar block. The silt deposition made Mangala cut dynamic and the mouth of the cut has shifted towards north direction. For discharging water, the cut open its mouth naturally in August 2016 near hotel Sterling. The objective of the present study is to analysis the spatio-temporal dynamic of the Mangala cut. The study area is the Mangala cut, which situated 19°46ʹ46.227ʺ to 19°48ʹ16.849ʺN latitude and 85°46ʹ48.135ʺ to 85°47ʹ22.858ʺE longitude. The study has taken during the year 1929 to 2016 and the US Army Corp engineers’ toposheet of the year 1929 has taken as base year before the cut made and 1973 Survey of India (SOI) toposheet has taken for after the cut made. In between 1937 and 1973, the study has not taken because of lack of data availability. For analysis the dynamic of the cut, the geospatial technology has used for regular monitoring of the cut. The geospatial technology has emerged as the most important tool of a geographer to handle spatial data. This technique is now widely used around the world to analyse physical as well as cultural geographical elements. The SOI toposheet and the spatio-temporal satellite image has used for interpretation of migration of the cut which are utilized in several regional planning and management for community development.
