Digital Elevation Model is a Tool for Terrain Analysis: Implication and Interpretation with Reference to Kuya River Basin

This paper aims to present terrain characteristics of Kuya river basin specially relief zoning, aspect analysis, hill shade view, its relation with drainage conditions etc. Analysis of SRTM data in ERDAS Imagine and Arc GIS software reveals that there is no siginificant relief difference between upper and lower catchment of the basin but distinction between upper and lower catchments is very clear by topographic break of slope along 80 m. contour level. Aspect analysis propounds the fact that there is very clear cut difference between upper and lower catchment which is demarcated by coarse aspect texture in upper and fine aspect texture in lower catchments. Accordance between topographic character and drainage character shows there is no remarkable structural control on drainage alignment.
