To investigate magnitude of soil variability in morphological and other characteristics across different landscapes in the Siwalik hills, remotely sensed satellite data of IRS-lB-LISS-I have been analysed. Five different landscape elements (shoulder, toeslope, backslope, footslope and rivnlet) in the Siwalik hills in semi-arid tract of Punjab have been encountered. A statistical analysis of horizon thickness determinations showed a consistently wide range of variability within the different landscape positions as indicated by high standard deviations and coefficient of variations. The soils developed on toeslopes showed thicker horizons whereas shoulder slope showed thinner horizons with minimum solum thickness. A statistical calculation showed highest variation amongst clay and silt, organic matter and calcium carbonate but there was no difference in pH and EC.
