Abstract:
يعد وادي المعاذر احد وديان الهضبة الغربية، ويقع ضمن مدينة الرمادي التابعة لمحافظة الانبار، في الجزء الشمالي الغربي من بحيرة الرزازة، اذ يحتل الحوض مساحة بلغت (40,031كم2) موزعة على (4) احواض ثانوية.تم التعرف على طبيعة الخصائص التي تمثلت بالبنية الجيولوجية | Al - Maathir Valley is regarded one of the valleys of the westren Plateau. it is located within the city of Ramadi in Anbar. In the North - westren part is Alrazzaza Lake - and the basin occupies an area of about (40.031 km2) distributed into four sub - basins. The nature and the physical characteristics which represent the geological structure, climate, topography water resources, soil and natural plants were recognized, their effect vary in the formation of the land forms. The geological structure had a role in the area of study. From the stratum side, the prevalent rocks are the calcareous and gypseous and salt (NaCl) which has the ability to melt , but especially the sandstone, mudstone and the potter clay stones. Morphologically, the basin is located in a region that was effected by the cleaves, taps and crack. These are weak points. The topography of the area is relatively low. The basin is within the lower valleys, the general inclination of the region is towards Alrazzaza lake to the east. The old climate has a role in the geomorphology of the basin area in terms of the lands forms less intense than in the Plaestcyne Age. Water resources contribute in assessing the volume of water revenues and how to make use of it. Groundwater represented in two activities : the first is the chemical activity, represents the melting of process before the land form calricine, while the second of the mechanical activity includes the process of damping the rock which lead to its collapse. The soil represent the bottom of valley soil, mixed desert gypsum soil, salt soil, sand soil. While the natural plant was characterized by the variety and rarity including the longevous plants and annual plants. The quantities analysis was made to the features of the fluvial network, including the area and form, and the topographical morphological features and knowing the fluviatile forms. The land forms were classified into nine different forms resulting from (morphological land forms) and the land forms resulting from downfall, forms and land form resulting from the water disrobement and land forms resulting from the ridging predisposition and the land forms and finally man - made land forms.
