| Abstract | ||
| The river valley landscape, as a geomorphological unit, is considered a product of the river stripping. Therefore, the structural phenomena and the subsequent movements affect the basic forms of the river valley, in addition to the human uses after the erection of the dam. Al-Utheim River is one of the Tigris tributaries which lies in the dry and semi-dry province. It is the only tributary which flows from the Iraqi territories and pours into Balad District- Tikrit Governorate. The significance of this study is represented in the follow up of the river behavioural changes which led to the formation of the river landscape after the erection of the dam and their consequences on the use of land by the inhabitants of this area. The follow up to the geomorphological changes (before and after the erection of the dam) was carried out with the aid of the space data of the American Satellite (5-7 TM Landsat) ( 1990-2009) , the data of the space satellite Echonose, topographical maps (1/20000 ) and geological maps, the soil and the land use. The study is assisted by a field work to the area using the programme ArcGis9.3 to conduct a spatial compatibility, to draw, classify, and analyze maps. The field work also contributes to find out the behavioural change in the area under study and its impact on the river region to take the proper decisions regarding the significance of such topics in the spatial development. | ||
