Abstract:
ان الهدف من الدراسة هو بيان الخصائص الهايدرولوجية والجيومورفولوجية لحوض وادي ابو مريس الواقع في الجزء الجنوبي الغربي من الهضبة الجنوبية بمساحة(332,148) كم², امتدادا من حدود محافظة المثنى مع محافظة النجف تحديدا شمال غرب بحيرة ساوه، المحصورة بين دائرتي عر | The aim of the study is to show the hydro - geomorphologic characteristics of Abo Morais valley basin which lies the south western part of the southern highland with an area which extends (332, 148 square kilometer) from the borders of Al - Muthana province with Al - Najaf province specifically to the north west of Lake Sawa which extends between (31, 22 - 30, 56) latitudes northward and (45, 30 - 44, 30) longitude eastward. The study deals with physical characteristics of the area showing the spread of formations of the Eocene epoch represented by the formation of Al - Damam, Euphrates, cave and the deposits of the Pleistocene epoch represented by the deposits that fill the valleys, downhills and wind deposits via the morph - metric analysis of valleys of the study area, it has become clear that the valley have taken the rectangular shape that the elongation rate (0.4) in the whole basin of Abo - Morais because the study area was affected by faults and gorges. The hypsometric coefficient of the basin was (13, 45) which indicates the beginning of the geomorphologic development of the basin. Hydro - logically, the hydro - equation shows that the area suffers from water shortage in nine months extending from(March to October) while in (December, January, February) Al - Samawa (15, 12mm ) in Al - Najaf plant. SCS - CN equation has been used to estimate the size of the flow which depends on the soil type of basin and its permeability. Earth cover type of the basin have been classified to calculate CN values which indicate that the rate of CN value of the whole basin was (82, 50) which is a high value referring to the valley permeability deficiency. The roof low size for twenty years amounted to (33, 42) million square meter which is a step to apply the water harvest technique in the basin of the area due to its hydro - geomorphologic characteristics. As for the supply of the ground water, the water leaking through the soil and porous rocky layers of the same valleys reached (18,3 - 11,7) million square meters. This amount of water constitute the so - called ground water renewable storage. The study determined the validity of the ground water for the different human purposes whether potability or using it for the industrial and constructional irrigation. It has become clear that the ground waters are not valid for the human use and valid for purposes of plants and animal irrigating and for industrial purposes. The study determines the suitability of the lands and classified the ground cover and also showed the ways of developing its resources.
