Soil Uniformity and identification of lithological discontinuities in some soil series of the districts surrounding the Fallujah city of Anbar Governorate.

Abstract

To know the uniformity of soil and identification of the cases of lithological discontinuities, this study was conducted, including twenty alluvium soil series distributed geographically toward the north, south, east, and west of Fallujah. Five uniformity ratios were adopted that were applied to the soil separately. And then, the lithological discontinuities were determined in them, as well as showing the effect of fluctuation of the groundwater level in the variation of these ratios between the soil series and the district. The results showed a large variation in the uniformity value between the soil series on the location and between the district, depending on the sub-physiographic location. The result also showed a significant correlation between uniformity value and groundwater level in the region.
