Foundations of buildings in a Roman city in England could be easily discovered using standard processing methods, but a more detailed analysis of reflection profiles after re-processing and a comparison of GPR images with magnetic gradiometry maps provided information that allowed for the functions of come buried buildings and also an analysis of the city’s destruction by fire. In addition to the structural control over landform distribution, occurrences of paleo and current bank breaches were also recognized. India, has been a religious and cultural human settlement for over 2000 years of zone suggest deposition during a major catastrophic flood. Note the sudden offset of about 6 m (refer to (a)) along the tectonic line of, deltahead of the Kaveri River. With the advent of sophisticated data acquisition, and processing techniques in recent years (Booth, Linford, Clark, &, Murray, 2008; Conyers, 2011, 2012, 2013, 2015, 2016; Conyers &, Leckebusch, 2010), GPR provides useful information in the form of, 2D and 3D representations.

Edited by My.Ramkumar, Arthur James, David Menier, K.Kumaraswamy, The Srirangam interfluve, formed between the Kaveri and Kollidam Rivers in southern India, has been a religious and cultural human settlement for over 2000 years of recorded history. We propose geomorphic isostasy as the mechanism that has driven this fastest drift ever recorded in geological history.

Specifically, a remote sensing approach around the monastery including aerial survey by unmanned aerial vehicle (UAV), ground-penetrating radar (GPR) and geomagnetic survey in gradiometric configuration (MAG), was adopted in order to verify the possible existence of buried masonry structures and other possible features of archaeological interest, including channels and aqueducts. been, and continuing yet, since prehistoric times, a thriving religious, cultural, agricultural and human settlement. It contains thousands of ancient, yet in use, man‐made structures. Traditional site planning of temples/houses adhere strictly. Giosan and co-workers contend that the 'mythical' Saraswati River was not a glacier-fed Himalayan river.

Amidst these, occurrences of tectonically quies-cent regions and multiple incisions by river channels and flow of modern river channels in inherited palaeovalleys but on tangent directions of ancient flows are also observed. This places a severe constraint on the understanding of the regional ception of GPR are more accurate than other geophysical techniques. Thematic maps of geomorphology, vegetation index, land Five stages of landscape development are envisaged: First, inheritance of river basins from palaeodrainage systems; second, reversal of river flow directions during early part of Cenozoic and inception of evolution of modern river systems; third, during Miocene-Pliocene; fourth, during Pleistocene-Early Holocene; and fifth, during the Holocene-Anthropocene.
