Quantitative analysis and their interrelationships are very important to understand the hydrological responses of the drainage basin and to analyse the approximate behaviour of that basin which is the response of different physical parameters of any region. Earlier the conventional methods were used for morphometric measurements of the basin but now-a-days remote sensing and GIS tools and techniques are used to analyse, to update and correlate the drainage morphometric measurements with periodic changes. This study focuses on the relationship with terrain and river basin, along with the nature of the basin; and for basin management and combating natural hazards through measurement of linear, aerial, and relief aspects using remote sensing and GIS. Here, morphometric analysis has been done by using 30m ASTER DEM and ArcGIS software to examine various aspects of Sagileru River basin, a tributary of Pennar River, Andhra Pradesh. The result shows 7 th order stream with total stream length of 5450.34 kms and mean stream length ranges from 0.59 to 81.07 kms and mean bifurcation ratio is 4.29. Where relief aspect analysis shows that maximum, nearly 38.88% lies in low elevation zone (200m – 400m), closely 45% area comes under the low dissection index zone with 86% area categorised as very low rugged area, means mostly characterised with gentle slope. Areal analysis shows that maximum area of the river basin has low drainage density, which shows old stage of the river basin. Overall it refers that the examined basin area mainly developed on homogenic geological structure with less rugged variation. Even sub-basins are also approaching to old stage. This study may help to the planners, researchers, local and regional government to take necessary stapes for overall basin management and development.
