Cartographic representation of the risks the eastern part of the geomorphological to spend Sheikh Saad in Wasit province using geographic information systems.

Abstract

Provides geographic information system easier ways and means to read a map and planning that is required according to the rules of the available data on these map and analysis of aerial photographs and read and sorted also offers advanced techniques in geographic database management and quick searches (Find) At the inquiry processes (Query) as well for representation on the maps with the possibility of making comparisons in a manner identical (Overlay) and directed by the required information. Can use GIS technology to jimorvologih risk with reference to the risk of erosion, as is the index in the current research, as it has been the study of the spatial relationship between soil erosion and decline in the district of Wasit, based on a set of the subject and of a map regression and ranges erosion and topographic and discover spatial relationship maps between erosion and slope, and show through matching that there is no inevitability of the characteristics of the regression slopes, especially with high erosion ranges relationship. Therefore, the ultimate goal of this study is to give value to the technology of geographic information systems in the study of the natural components of the environment, especially the soil and protect it from degradation and erosion and the relationship of that variable ground slope. And exit models cartography help understanding and clarification using geographical and modern technology systems.المقدمة
