الملخص EN

This study was conducted to recognize and explai the variation in some physical and chemical properties of soils, banks and river basins in Abi AlKhasib District (Basra Governorate).

(28) samples were collected in order to achieve this aim.

After the field survey has been done, the coordinates of those samples were determined using GPS and placed on the map of the study area to produce maps of spatial variation and spatial analysis, and then the samples were sent to the laboratories of the College of Marine Sciences at University of Basra.

Volumetric study of soil separations revealed that silt particles predominated on river banks, whereas clay particles predominated in basin soils, with averages of (49.42 - 64.77 %) and (49.42 - 64.77 %) respectively.

In comparison to the standard, the results revealed a high bulk density value.

Due to the low amount of organic substance in it, the true density fluctuated in height.

The results also revealed that owing to the kind of tissue and the presence of organic debris, there is a minor variation in the porosity values of the sites and the guarded depth.

The chemical analysis showed a decline in soil organic matter content and occurrence within the soils category and organic habit category in the Iraqi standard, with an average of (4.58-4.32 g/kg) for banks and ponds soils, respectively.

In terms of PH interaction degree values, the study area was classified as simple basal to medium or neutral basal.

With the height of the basin trail, all of the sites were between the types of high salinity and very high salinity in terms of soil salinity
