Abstract
Due to its use in numerous geological and biological contexts, morphometric analysis has drawn more attention in recent years. It offers perception into process-associated modifications together with catchment assessment, runoff, infiltration, watershed development, natural and structural frameworks. Study of the Thamirabarani river is composed of Achaean crystalline rocks in the west and tertiary and quaternary sedimentary rocks on the east coast. In the current work, a morphometric analysis of the Thamirabarani river was performed to describe the various surface processes that cut the watershed into the river topography. Catchments were defined using Cartosat data and Arc GIS 10.4.1. This study shows that the stream varied from 1 to 5 (I-357, II-89, III-21, IV-9 and V-3) orders. According to the mean bifurcation ratio, the stream is topographical and complex regulated in its shallower parts. The analyzed basin's high permeability is explained by the studied basin's low current frequency values. Plate erosion rather than channel erosion can be seen in overland flow lengths (>0.14) and rough textures can be seen in drainage patterns. Asymmetric and extended basins with neotectonic activity are indicated by analysis of measured parameters using morphometry. Therefore, various interpretations are produced based on morphometric test of the Thamirabarani stream system to help provide information pertinent to social benefits.
