Abstract:
The Study aims to detect natural factors affecting the formation of sand dunes in AL - Rifai Distrect, and showing their effects on the geomorphic operations and disclosure of the nature of the operations geomorphic processes, measuring their activities, knowing their immediacy and future effects, identifying the shapes of the prevailing sand dunes in the raised by environmental and identify forms of sand dunes prevailing in the region, and measuring their dimensions and activity and knowing their effects in the region and producing a Geomorphic detailed map including most units and Geomorphic appearances inside it, and discovering the mutual effects between the sand dunes and its impact on human activity in the region to evaluate natural resource , The study area is located administratively in the northern part from province of Dhi Qar province, which is bounded by north Wasit province, on the east by Miysan province , on the west AL - Qadisya and simawa provence and from south by Shatra District , and from southwest part by AL - Batha Locality , Astronomically located between latitudes(32 - 31 20) north, and the length between the brackets(45 45 - 46 20) east, As it can be seen from the map (1). The area ( 3.300)kilometer (1,320,000)acres. an estimated 25,58% from space Dhi Qar.the study Included of four chapters , first chapter shows the natural factors that effecting the formation of sand dunes, which at geology study area and general surface characteristics and climatic characteristics of the water situation and the characteristics of soil and the characteristics of natural plant ,chapter two included geomorphic processes prevailing inthe study area, which includes the morphomanakhic processes of chemical weathering and physical weathering the biological ) as well as wind erosion processes and al Heidrogiomorvih operations which is presented by ( The emanation deltas). These processes according to their impact on the formation of sand dunes as an aspect of the ground , Chapter three clarifies the Sand dunes geomorphic turning to the (volumetric analysis for the sandy sediment by using the constant statical and the formal characteristics for the sediment. It also interested in analyzing the morphometric characteristics of the sand dunes , such as the movement of the sand dunes , the geographical distribution and the most prevailing forms of sand Chapter four devoted to the study and research of the applied aspects by clarifying the impact of the sand dunes on the human activity , which is presented by geographical distribution the irrigation and drainage projects, residential areas, agricultural activity, transportation and the human health, The study has been ended with some conclusions and suggestions.
