The Dynamics of Sedimentation in the Nile River and Its Effect on the coalescence of Shaybah and Ash-Shaykh Timay Islands in the Flood Plain, Minya Governorate By Using Geographical Information Systems and Remote Sensing

The Dynamics of Sedimentation in the Nile River and Its Effect on the coalescence of Shaybah and Ash-Shaykh Timay Islands in the Flood Plain, Minya Governorate By Using Geographical Information Systems and Remote Sensing Abstract The sedimentation process plays a major role in the geomorphological changes in the Nile River, especially the alluvial islands from the beginning of its formation until their coalescence with the flood plain. Such process is applied to the islands of Shaybah and Ash-Sheikh Timay through studying the physical and human factors affecting the dynamics of sedimentation through establishing geographical database containing hydrological, morphological, geomorphological and human variables in the study area. Geographic information systems (GIS) and remote sensing (RS) are used to determine the areas and rates of sedimentation during the comparison periods and their role in the coalescence of the two islands. Keywords: sedimentation, alluvial islands, flood plain, geomorphological changes, geographic information systems, remote sensing.
