Detection of Changes In Nubian Lake Using GIS and Remote Sensing

Abstract

The Nubian lake is one of the largest industrial lakes resulting from the establishment of High Dam in Egypt and is located in the Sudanese-Egyptian border. This research deals with the study of changes in Nubian Lake using Geographic Information System and remote sensing. The ArcGIS capabilities had been utilized. The Remote sensing technique had been applied to assess the change that occurred at the lake boundary. Moreover, the urban development and the increased in the agricultural area between 1985-2017. The curve of change of the lake boundaries had been prepared and analyzed to figure out the reasons for the increasing and decreasing in the lake boundaries and the lake areas had been obtained during the periods of study, also the residential and agricultural areas had been calculated during this period. A model had been designed to replicate the classification process and to use it to reduce the lost time in the single classification process and the necessary steps to find the lake boundary; this model can be used automatically in studies similar to this study. Finally the outcomes of this thesis indicate that there are changes in the shape of the lake weather it is increasing or decreasing, also the growth in the town had been extended; in addition to that there is no significant increase in the agricultural areas.
