摘要

Study of drainage and basin is important to understand the character of any basin geometry for implication of conservation of natural resources. Remote sensing and GIS is valuable tool and widely used in recent research for geometric analysis of basin. SRTM data was used to delineate the drainage network as well as sub-basin boundary; digital elevation model, aspect grid and slope map were prepared using SRTM data. Morphometric parameters (linear, areal and relief) has been analysed with the help of ArcGIS 10.2. in this analysis mean RB varies from 2.31-3.97, elongation ratio is 0.63-0.9 and relief ratio is 0.033 to 0.06; indicates that the area is highly structural controlled, steep ground slope, high drainage density and sub-dendritic to sub-parallel nature. These studies are very useful for understanding the structural control and inequalities in the rock hardness for the Ataq region.
