المستخلص: The present study aimed to delineated the geomorphologic features in the area bounded between Shatt Al - Arab and Khor Al - Zubair by means of Remote sensing and Geographic Information system (GIS) techniques, southern Basrash city. The study traversestarted from Al - Saraji River in the north to the shore line of Arabian Gulf (Ras Al - Bisha) in the south. To acieved this study the researcher adopts four main methods : descriptive (filed trips), origin, development, and quantitative methods, the last one comprises theanalysis of texture and other physical and chemical soil properites, as well as, the using of GIS technique, i.e., the using of satellite image which supplied by the Landsat - 7, this image has many bands;1,2,3,4,5,7, and 8 bands, the sixth band was excluded because of its thennal nature which is out of the present study scope. To present a full desctiption and explanation for the geometric features, the data bases was employed for maps construction, the satellite images was subjected to many soft maps construction, the satellite image was subjected to many soft ware program to carried out engineering correction, digitization management, and position analysis and date base builddup to achieve the necessary maps. The information abstracted from the image analysis in addition to the physical and chemical properties of the study soils enable us to categorized the observed geomorphic features into four main unit; natural levees, transitional lands, sabkhas, and tidal flats, furthermore 1l is also thepresent present study emphasized the activity of GIS in offering time and efforts in studying the natural phenomena incomparsion with the traditional methods, moreover the GIS provide us with high flexibility in controlling the scale of the prepared maps. Regarding the physical and chemical weathering processes, the present study proved that the extension, contraction, dryness and wethess process play an important role in physical weathering which seems to be the dominant processes incomparsion with chemical one. The deposited sediments of both fluvial and Aeolian origin yield new lands, the continuous sediments deposition during 1983 - 2002 period creating a new land with a total area of about 92278 square meters.

المستخلص: influence and determine the quality of air pollutants in Al - Basrah governorate. It deals in details with the most crucial human an natural pollutants air factors such as rain falling , dust , lead in domestic dust , the acid rain degree , the concentrations of some gases (Oxide and amoniaoxide Carbon, amoni - oxide Sulfuric , Hydrocarbons , Chlorine , di hydrogine sulfur and Amonia ) throughout the area using (Aspirating Pump OS 50) and some bottles fir measuring atmosphere gases in part per million (ppm).The study falls into four chapters. Chapter one deals with the ·theoretical and systematic of the thesis , chapter.utwo tackles the natural factors that influence , positively or negatively the problem of the study , Chapter three discusses the human factors that help in causing the problem And chapter four includes a locational analysis of the most important air pollutants throughout collecting and measuring them and reaching at their concentrations.The study arrives at the following conclusions : 1. The astronomic position determines the climatic characteristics of the study area for it falls in the dry region which is reflected on the other natural factors and their effects on the distributions and concentrations of these pollutants.The geographical position of the study area , which is adjacent to Thi - Qar governorate which has the highest repetition of dusty and sandy storms in Summar , has a negative effect in increasing these pollutants in this area. In addition , there are some oilycountries adjacent to the study area that have an important role in casting much of these pollutants.The flat surface helps in activating the role of the wind in spreading the air pollutants and never be concentrated in certain places. This decreased the problem of air pollution.The climate causes the aridity of the soil , and fewness of the natural that supports the raising of the striping operation and the oxidation of the elements and gases that cause air pollution.The sandy dry soil has a negative role because of the easiness of its denudation by the wind which causes air pollution in the western part.Even water helps in absorbing some of the air pollutants and finding agricultural distances and natural plants. However , this factor looses much of its vital role because of the human interference in its pollution by drying out most of the marshes.The scarcity of natural plants has a negative role in protecting the air from pollution. The population which is (2100326 person) fling rubbish to the environment without any remedy. This increases the problem of the study.9. The fewness of the agricultural areas influences in increasing the problem of the study , in addition to the use of the chemical and organic fertilizers , insecticide and others.10. The increasing number of vehicles from (51383) at 2003 to (104012) at the end of 2004 increas air pollution. 11. Most of the environmental pollutants was resulted from some essential industries.12. The wars plays a great and danger role in destructing the environment.13. The highest average of the falling dust in the western side in Qhur Al - Zubair was (71.9) g/m2 , and the lowest average in the eastern ,., ~ side in Abu Al - Khaseeb was (38.6) g/m2 14. The amount of (Co2) exceeded its natural concentration (0.03) ppm. The highest concentration was (0.08 - 0.3) ppm and the lowest was (O.Ol)ppm.15. The oxide Carbon (Co) exceeded its natural and permitted concentration. The highest polluted concentration of the gas was (80 - 100) ppm, and the lowest was (5) ppm.16. The concentration of the polluted sulfur Dioxide (So2) exceeded its natural and permitted concentration the highest polluted concentration was (20 - 30) ppm, and the lowest was (10) ppm.17. The hydrocarbons had polluted concentrations exceeded permitted ones , as the highest polluted concentration was (10 - 20) ppm, and the lowest was (5 - lO)ppm.18. The chlorine gas has polluted concentrations exceeded the permitted ones, as the highest concentration was (1.0 - 2.0)ppm , and lowest was (5.0 - 1.0)ppm.19. The Hydrogen Sulphide (H2S) has polluted concentrations the highest was (3 - 5) ppm and the lowest was (2) ppm. 20. The Amonia (NH3) gas has polluted concentration , the highest was (10 - 15) ppm, and the lowest polluted ones was (5) ppm.21. The highest average of the obstacles concentrations that contain lead (pb) was (2112.84) mlg/m3 , in which the percentage of the lead was (0.515)ppm in the southern sandy side , and the lowest concentrations of these obstacles that had lead of about (1623.28)mlg/m3 and (0.258)ppm was in Sa'ad Sequare.22. The concentration of the lead in the demostic dust is (0.033) ppm in Al - Basrah and (0.030) ppm in Al - Hartha.23. The (PH) of the falling rain varied between (6.9 - 8.4) , the highest one was (8 - 4) in Al - Basrah , and the lowest was (6.9) in Al - Qurna.
