Description
India has 7,516 km of coastline, of which the mainland accounts for 5,422 km. The shoreline is one of the rapidly changing linear features of the coastal zone which is dynamic in nature. The issue of shoreline changes due to sea level rise over the next century has increasingly become a major social, economic and environmental concern to a large number of countries along the coast, where it poses a serious problem to the environment and human settlements. Shoreline recession as a result of rising sea level has been recognized as a potential near future hazard by a number of countries and this is same for the states of India along the coast. Today the issue of shoreline changes due to sea level rise caused by Globe warming has increasingly become a major issues in terms of its impact on the population along the coastal area. Changes in mean sea level as measured by coastal tide gauges are called relative sea level Changes. In IPCC (Intergovernmental Panel on Climate Change) Third Assessment Report (2001) shows that global average surface temperature is projected to increase by 1.4 to 5.8° C over the period 1990 to 2100. The present study deals with the morphological modification manifested along Ongole Coast, Southeast Coast of India. Satellite imageries of the study area for February 9, 2010, March 18,2012, May 27,2014, and April 30,2016 were used. This study was carried out using multi temporal satellite images of IRS P6 LISS-III and Landsat 8 OLI/TIRS data from 2010 to 2016. Visual interpretation techniques were employed to establish the morphology categories from Satellite Imageries year-wise. The study shows that there is a constant changes of the shore owing to the both natural and anthropogenic activities. The impact of global warming-induced sea level has great significance to India due to its extensive low-lying densely populated coastal zone. This paper attempts to find the time trend of the sea level rise and document the positive, significant and increasing trend for the majority of the monitoring stations along east coast of India. In order to avoid further damage to this coastal fragile ecosystem immediate safety measures have been suggested to the policy makers, public etc., .This paper attempts to provide action plans for the policy makers to frame ideologies for the protection of the coastal environment.
