A Study of the Areal and Relief Morphometry of Suktel Basin, BolangirDistrict, Odisha

Abstract

In the present study, an attempt is made to study the areal and relief aspects of morphometry of Suktel
River, a tributary of Tel River and its subbasins that flows through Bolangir District of Odisha. The study is
done using SRTM dem and GIS. Freely available SRTM Dem (30-meter resolution) has been processed to
delineate the streams and the watershed. Its various linear, aerial and relief parameters have been
delineated using Arc GIS 10.3. The results show that Suktel basin is a sixth-order basin having a dendritic
drainage pattern. It has an elongated shape with coarse drainage texture. The highly concave upward
hypsometric curve and low integral values ranging between 0.12 and 0.19 for the study basin and its
subbasins imply that the basin is in the monadnock phase of basin development characterised by flat
terrain with very low relief.
