Abstract:
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.
