<p>The Eastern Ghats of southern Tamil Nadu is composed of prominent delta valley of the river Cauvery. Being a perennial river, Cauvery extends its sub-watershed across the paths of Salem and Namakkal. It is evident to measure and put forward the pavement of this river across the study area. This paper uses the images of LISS 3, SRTEM; constructive and destructive analyses are further carried out with the above images. This basin area of sub-peninsular extends over different morphological area of the delta valley. The study is coupled with the information delivered by the survey of India toposheets. The morphometric and anatomical analysis is carried out by employing ArcGIS 9.1 software platform. Various theoretical and visual aspects of the basin are analyzed and interpreted, especially the remarkable hindrance due to astounding influence of geology, geo-morphology and tectonics of the basin. The results are discussed in this paper. Digital Elevation Model for the study area is prepared using ERDAS IMAGINE 9.1. © International Science Press.</p>
