Abstract:
تهدف الرسالة ( جيومورفولوجية مصب رافد الزاب الصغير - نهر دجلة ) الواقعة بين دائرتي عرض ( 01، 21، 35، 29، 06، 35 ) شمالا، وبين خطي طول ( 35، 32، 43 ـ 14، 22، 43 ) شرقا، الى الكشف عن العوامل المؤثرة في تشكيل مصب النهر من جهة وتوضيح علاقة الارتبا | The thesis, Geomorphology of Eusteral of the Lower Zab, Tigris River, which lies between the latitude (35, 06, 29 - 35, 21 , 01) North and longitude (43, 22, 14 - 43, 32, 35,) East, aims at discovering the factors effecting the river eustoral from one side and clarifying the connection relation between the terrain units and their reflections on the distribution of settlements and the land use. It made use of methodology adapted by (ITC) Institute in analyzing the effective environmental components in this formation, using remote sensing techniques and GIS to design the related maps. It used satellite data Land Sat - 1Mss (1973) - Land Sat - 7 ETM (2000), accompanied with processes of registration and enhancement to clarify and facilitate its supervised classification. It also used radar data received in 2000 though which relief (elevation and slopes) construct the 3D (DEM) and show the effect of the structure factor in its formation. The study also studies the morphological characteristics of channel river patterns and found the relationship with its forming factors, (structural, climate and hydrological factors) The study contains four basic chapters; • Chapter One : deals with methodology of the study and its theoretical frame.• Chapter Two : concentrates on the constructing factors of the environment of the eustoral.• Chapter Three : consists of an analysis for the morphotectonic and relief and analyzing the river channel.• Chapter Four : concentrates on the land classification of the eustoral. And contained the terrain units and patterns of land use and also suitability and land capability.The conclusions of this study are : • It becomes clear that the area was affected by the Geographical Alpine movement accompanied with structural deformities that affected the shape properties of the Lower Zab. • The Quarterly Age Climate plays a significant effect in the changes occurred in the hydrological properties and their effect in the shape properties and terrain units.• The study shows that the Lower Zab is undergoing processes of dividing and islanding which means the dominance of braided patterns and the muchness of minor channels and their incessantly in the drought years as the isles with irregular form are the dominating property in their existence.• The existence of the small river bends with the muchness of the deep and shallow positions in the river waterway due to mix loads. • In the Lower Zab waterway dominates three types of floods; normal, exceptional and overwhelming floods. The first is the most occurring because of man’s control of this river through constructing dams and reservoirs (Dokan and Dibs Dams).
