Abstract
Absteact : Al-Qaara depression was chosen (179670.8 h ) which is located between 40.0 – 40.50 longitude east and 33.033.40 latitude north in western desert of Iraq to implementation f of study using satellite image land sat – 7 interpretation and analysis satellite image by analog and digital addressing . tow transects was chosen the first was 7km and the second 21km the studied pedons were determined by GPS, the top contour line 650 m and the lowers was 450 m above sea level . the slope percentages ranged between 0.08 – 15.89% ,and slope classes ranged between the level slope to strong slope. The results showed a mach between the geomorphological maps and soil maps , the result showed spatial variation for some soil properties with slope , the soil depth ranged between ( 60 - 125 ) cm , and the thickness of A horizon ranged between (20 – 35 ) cm,while the thickness of B horizon ranged between 15-55cm for tow transects . And observed the dominant kaollinite mineral in the upper parts of the slope , while the dominant palygorskite mineral in the other parts of the slope .
