The study area, Tehran-Karaj plain is situated in  central part of Iran, lies between  latitudes 36°10′  to 35°04′ N and longitudes 50°38′, to 51°45′ E covering an area of 4762sq km comprising of 4 sub-watersheds (A,B,C and D). Morphometric analysis is important in any hydrological investigation and it is inevitable in development and management of drainage basin. The present study involves the Geographic Information System (GIS) analysis techniques to evaluate and compare linear relief and aerial morphometric of the 4 subwater sheds. The drainage network shows that the terrain exhibits dendritic to sub-dendritic drainage pattern. Stream orders ranges from fourth to fifth order. Drainage density varies between 0.21 and 0.4 km/km2 and has very coarse to coarse drainage texture. The relief ratio is ranging from 0.004 to0.017. The mean bifurcation ratio varies from 2.37 to 3.77 and falls under normal basin category. The elongation ratio shows that ‘C’ watershed possesses circular shape while remaining sub-watersheds mark elongated pattern.
