Master's thesis at the University of Basra discussing (geomorphological analysis of the Karun River course)
A master’s thesis in the Department of Geography at the College of Education for Human Sciences at the University of Basra examines (geomorphological analysis of the course of the Karun River and its effects on the Shatt al-Arab river) by the student (Sada Sadiq Yaqoub).
The study aims to study the geomorphology of the course of the Karun River and its effects on the Shatt al-Arab by studying the factors and processes affecting the course of the Karun River and the geomorphic forms present in the riverbed. And analysis of the morphometric characteristics of the landforms of the Karun River course, which include the morphological, topographical and spatial characteristics of the land features, as well as the analysis of the characteristics of the water network in the region, which is related to its relationship to the hydrological and geological variables of the region, for its clear impact on the morphometrics of the landforms in the region. Clarifying the most important effects of the Karun River course on the Shatt al-Arab, especially the geomorphic, hydrological and political effects. Drawing a geomorphological map of the river course contributes greatly to providing a comprehensive vision of the development of the land features that formed in the course of the Karun River.
The study included four chapters, preceded by an introduction containing the importance of the study, its problem, hypotheses, objectives, location, methodology and stages of the study, similar studies, its structure, followed by conclusions and recommendations, a list of Arabic and foreign sources, and a summary in English
The study concluded: It is clear through the geomorphological analysis of the Karun River course and its effects on the Shatt al-Arab course, that the study area consists of (166) linear phenomena, and it was also found that there are five protrusions. The sediments exposed in the study area date back to the third and fourth time. The soil of the study area was formed by the sediments that were carried by the Karun River as a result of the floods that occurred in the area or through irrigation operations. As the hydrological characteristics show, there have been significant changes in the quantities of water discharge, levels and river load, especially in the recent times due to the erection of many different dams. The study also showed that the human factor left an impact on the geomorphology of the Karun River course as a result of the construction of dams, reservoirs, iron and concrete bridges. It also showed the discrepancy in the real and theoretical length of the stream, as its real length was (259.08) km2, while the ideal (theoretical) length was (101.9) km for the year 2020. aging in its lower parts. It was also clear that there were (40) torsions within the longitudinal sector of the stream, varying in their morphometric characteristics and distribution during the longitudinal sector of the stream. And the quality of the Hetih phenomena in the study area, which are represented by river banks and river terraces, and other sedimentary phenomena represented by the shoulders of rivers. It was also found that there are (62) river islands in the river course in 2020.
