Abstract:
تم بحث هيدروجيومورفولوجية حوض وادي السدير باستعمال تقنيات نظم المعلومات الجغرافية (GIS)، الذي يقع اداريا ضمن حدود محافظة المثنى، وطبيعيا ضمن هضبة العراق الجنوبية، واحتل مساحة قدرها (1805.28 كم2) والذي يجري واحواضه الثانوية الاربعة مع الاتجاه العام للانح | The present study has investigated the hydro - Geomorphology of Wadi Al - Sadeer Basin which is located in Al - Muthanaa Governorate of the Southern Iraqi Plateau through the use of the geographic information system technology (GIS). Wadi Al - Sadeer Basin constitutes an area of about (1805.28 KM) which is running with its four sub - basins from the southwest to the north and northeast. Its astronomic location is situated between the latitudes of (29? - 53? - 41?) and (30? - 45? - 26?) north, and the longitudes of (45? - 31? - 44?) and (46? - 7 ? - 18?) east, that is, it falls within the climate of dryness and semi - dryness Iraqi region, and its water is running during the yearly raining season.This study is intended to identify the natural physical geography of this basin in terms of its natural processes and factors, featured draining systems and the morphological shapes of this basin. In addition, it is intended to identify the most prominent natural potentials of Wadi Al - Sadeer Basin like water harvesting operations, renewable wind and solar energy resources that can be utilized as natural resources. The natural physical resources comprise the ground structure, topography, climate, soil and natural vegetation. It is noted that the land structure has played a crucial role in the land formation, and the role played by the ancient climate conditions is of great impact on the geomorphology of the basin formation compared to current climate conditions. Besides the role of natural topography, soil and vegetation, is not less important than the aforementioned factors. The characteristics of water drainage network of the basin are analyzed according to the procedures so - called (Wadi Analysis) within the program applications of (Arcgis 10.2.2) operating in accordance with the methodology proposed by Strahler (1957). It consists of spatial, morphological, longitudinal and topographic characteristics of the basin and, the water drainage network. In addition, the analysis of hydrological characteristics of the basin is carried out in terms of quantitative and qualitative characteristics of water. The data analysis is based on the climatic information data provided by Asimawah and Nasiriya stations between the time periods (1984 - 2014). A set of equations have been computed to identify the quantitative characteristics of water resources. Also, the qualitative characteristics of specific samples of basins’ water have been checked to determine its safe use. Identification of geomorphological processes including the erosion and weathering operations and the like, has been done. It has been concluded that the water resources of Wadi Al - Sadeer can be exploited and used. Finally, the study has come up with a number of conclusions and recommendations
