A master thesis entitled (the sedimentary effect of the northern section of the Shatt al-Arab stream - a geomorphological study) was discussed in the Department of Geography and Geographic Information Systems at the College of Arts at the University of Basrah.

The thesis presented by researcher Hussein Yousef Abdullah included five chapters. The first chapter discussed the natural characteristics of the Shatt al-Arab stream, the second chapter examined the factors affecting sedimentation processes in the Shatt al-Arab stream, the third chapter dealt with the physical and qualitative properties of the Shatt al-Arab stream,  the fourth chapter dealt with the environmental effects resulting from sedimentation processes in the Shatt al-Arab stream, and the fifth chapter included the sedimentary morphology of the Shatt al-Arab channel.

The thesis aims to:

1- Evaluation of the qualitative and quantitative characteristics of the sediments of the Shatt al-Arab stream and their impact.

2- Studying the geomorphological change of the northern part of the Shatt al-Arab channel, through studying the most important geomorphological variables of the Shatt al-Arab channel.

The thesis concluded:

1- The northern part of the Shatt al-Arab represents a course with a special river system that reflects to a large extent the natural factors affecting its dynamics, morphology and sedimentation, which represent a reflection of the diversity of natural factors affecting it, represented by the geology of the river’s shape and its relationship with other variables such as climate, soil, vegetation, drainage, quality of sediment, and the amount of river load.

2- The lack of sediment in this part of the stream, which is due to the lack of river discharges. The only resource code for the river is the Tigris River, and it is also controlled in Qalaat Saleh through the dam, in addition to the lack of secondary rivers in this part, which reduces the process of hydraulic withdrawal of sediment, and the supply remains only from Banks breaking.
