Ground Penetrating Radar (GPR) is widely used for mapping of subsurface. Features in civil, geological, geotechnical, and geo- environmental applications. Considering the available technologies to map surface features, GPR techniques strands prominent in terms of its high resolution, and non destructive and cost - effective aspects. In this article, advantages and limitations of GPR techniques are presented. The usefulness of GPR application in buried coastal geomorphological mapping was discussed in detail, which is otherwise cumbersome with conventional methods. Four case studies were presented from different localities along the Indian coast. Based on the high resolution of the GPR data, buried geomorphological features were mapped accurately and the paleo- geological processes responsible for buried geomorphological features were discussed along with their evolutional trend. This type of information on buried geomorphological features is another important dimension of geomorphological studies, which helps to construct paleo- environment and processes.
