The study was conducted in order to classify Levee's Soil of Serwan river and to know
the dominant soil units in the study area, as well as to determine the dominant pedogenic
processes in the study area. Four pedons were selected along Sirwan River and described
morphologically. Soil samples were taken from each soil horizon to determine some
physical and chemical properties. The results showed that all pedons are developed with
A-B-C horizon sequences. All pedons have a Mollic epipedons with Agrillic and Calcic
endopedons. The The increase of fine and total clay are due to the activity of Eluviation
and illuviation pedogenic processes and to some extent to the new formation of clay
minerals. According to the morphological, physical and chemical properties of the
studied pedons, soils were classified as Typic Argixerolls as they have Mollic surface
horizons with more than 50% base saturation for more than 175 cm depth. They have
Argillic and Calcic subsurface horizons. The results indicated that the dominant
pedogenic processes affecting soil development are eluviation, illuviation,
decalcification and calcification.
