Abstract:
تناولت الدراسة مجرى نهر الفرات وتفرعاته والذي يمتد من ناحية الفضلية التابعة لقضاء سوق الشيوخ في محافظة ذي قار حيث تمثل نقطة دخول نهر الفرات في منطقة الدراسة، وتفرعه في هذه الناحية الى فرع (غليوين) والمقام عليه اول ناظم من نواظم الضبط الجنوبية وصولا الى م | The study examined the course of the Euphrates River and its branches, which extends from the hand of the Suq - Shuyukh in Dhi Qar province, where represents the entry of the Euphrates point Fudaliyah, and Tafrah in this area to a branch (Glujn) and place it first Rhyming of South head regulators tuning down to the mouth of the rest of the forest Euphrates River erected thereon Rhyming (Glujn, good vine, Aekakh, Digger, brown happy, or Palm) in Hammar marsh and along the river (43 km). Study of the hydrological system and the resulting forms of geomorphology and pictures invested in Hedrogeomorphology study. The researcher relied on field study scientific and historical sources and interpretation of satellite images and topographic maps.The study area is part of the alluvial plain land which is characterized by Banbsat out of the northwest slope towards the south - east, which Kan determine the general direction of the river bed a height of approximately (5 m) above sea level.The geology of the region dating back to the Pleistocene and Holocene era and covers the surface sediments of time is a modern four - wheel depositions disjointed divided into floodplain deposits, which mostly due to the activity of the Euphrates and tables branching ment in historical stages, depressions and deposits, and deposits of the marshes.The region is subject climatically to the dry desert climate depending on climatic data obtained from Nasiriyah station and Samawa, so the recipe drought to the region reflected its effects on the lack of rain in winter and high temperatures in summer, leading to variation and fluctuation in the discharge hydrological Euphrates River monthly and quarterly and annually and is affected by the quantities the disposal absolute headwaters of major river, affecting the composition of formats ground inside and outside of the river and its branches, as well as the lack of vegetation density, making the region is characterized by climatic water balance is negative, according to my way of Thornthwait and Khrovh. Based on these characteristics and how they interact with each identified forms the floor of the area and of Mounattvat and twists of river and islands river, which is that of the geomorphological aspects of excellence in forest river, as was the shoulder for (54) a turn and twisting in the main stream and the forest, and through maps and visualizations were taken clips longitudinal study area and Tzmt to three longitudinal sections where the river turned out to be going through a period where he excelled longitudinal aging sector of the river slightly Ptqar (semi - regular) to the small vertical distance of the sector for the longitudinal horizontal distance.As it has been cleared cross sections where it was found through a survey (10) sections of the river that the form of these sections take the form of the letter (U) which is a reference to the stage of aging is going through because of the duck runoff resulting from a lack of steep and deep (0.75 cm / km).As it turned out that there is a clear interaction between geomorphological fluvial processes and human activity as the changing course of the river through the stages may cause migration of many towns and villages that were built on its extension and turned into a new stream taken, which is reflected in the settlement pattern, as it would like linear pattern along the course of the Euphrates River in the regionAs it turns out that the river water is investing in several areas of agricultural investment in the forefront, and human use in the field of drinking comes lags filtered by the filter plants (RO) for use in the field of drinking and washing and then use the water to drink animals that grew up in the area and agriculture is dependent class basis on the style of irrigation through an intermediary only at the present time due to the low river water levels, through various pumps horsepower and powers on both sides of the river.
