Abstract

   The present study aimed to delineate the geomorphic features in the area bounded between Shastt Al-Arab and Khor Al-Zubair by remote sensing and geographic information system (GIS) technique, southern Basrah city. The study traverses started formal-Saraji River in the north to the shore line of Arabian Gulf (Ras Al-Bisha)in the south. To achieved this study four methods were adopted; descriptive (field traps), origin, development and quantitative methods, the last one comprises the analyses of soil samples for their textural, chemical, and physical properties, as well as , 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 thermal  nature which is out of the scope of the present study. To present  a full description and explanation for the geomorphic features the data base was employed for map construction, the satellite image was subjected to many soft ware programme to to carried out engineering correction. Digitization management, and position  analysis data base build up to achieved the necessary maps. The information abstracted from the image analyses in addition to the physical and chemical data of the soils under study enable us to categorized the observed geomorphic features into four main units; natural levees, transitional lands, sabkha and tidal flats. Furthermore it is also the present study emphasized the activity of GIS in offering time and efforts in studying the natural phenomena in comparison with 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 current study proves the extension, contraction, dryness and wetness processes play a major role in  physical weathering which seems to be the dominant process in comparison chemical process. The newly deposited sediments of both fluvial and Aeolian origin yield new lands, the continuous deposition extent from 1983-2002 period creating a new land with total  area of about 92278 square meters.
