Abstract:

This study aimed to experimentally examine the impact of organic matter content on some of compression characteristics of fine-grained riverine soils from southern Iraq. A total of eight soil samples were collected from two various riverine areas, presenting natural levee and basin (fine-grained) soils, in the eastern Basrah region. The research explored the correlation between organic matter content and compression characteristics, highlighting changes in unit weight, permeability, and compressibility. Fin dings showed that higher organic matter content led to lower density, increased permeability, and higher compressibility. The research offers valuable contributions to understanding the relationship between organic matter and soil compressibility, particularly relevant for sustainable soil management in the lower Mesopotamia region of southern Iraq, where those areas are vulnerable to climate change..
