Abstract: | Anandpur Sahib area of Rupnagar district (Punjab) was investigated using an integrated multi-disciplinary approach of geomorphological,
structural, drainage and morphotectonic analysis through satellite data and GIS. Most commonly used geomorphic indices viz.,
channel sinuosity, drainage basin asymmetry, basin elongation ratio, mountain front sinuosity and valley floor to valley width
ratio index have been used to identify the geomorphic indicators of active tectonics in the area. Existence of fluvial anomalies
viz., abrupt changes in flow direction, flow against gradient, beheaded streams and river terraces reflect the strong structural
control on the fluvial features. Asymmetric nature of drainage basin, elongated nature of the sub-watersheds, straight to
curvilinear mountain fronts and narrow incised valley floors further substantiate the role of active tectonics in the region. |
