Pedological Stratigraphy and the Effect of Groundwater Level on the Variation of Pedological Characteristics in Soils of some Agricultural Districts Surrounding Fallujah of Anbar Governorate

Abstract

This study was conducted in some provinces surrounding the Fallujah city of Anbar province, used soil texture to reveal the state of Pedostratigraphy between the soil pedons and the districts in all four directions. The study aims to demonstrate the effect of the Minder River and distance from the central and old branches of the river on the sedimentation processes and the uniformity of the soil separate, as well as revealing the reality and effect of the fluctuation of the groundwater level and its impact from the geotechnical in the future on these lands. The results showed the success of the soil texture class in establishing the state of stratigraphic correlation between the soil horizons of the provinces and study in all directions. The result shows the state of uniformity and non- uniformity between the soil separate from their horizontal and vertical distribution, in addition to the presence of significant differences between the provinces in terms of their particular distribution. The results also showed the effect of the depth of groundwater on the adequate soil depth, which was not affected by agriculture in all the study area
