Title: Dynamics Of Erosion And Deposition Of The Blue And White Niles At The Confluence AreaBased On Remote Sensing Techniques(Tuti Island As A Paradigm
Author: Sumaya Mohamed Awad, El Seed
Abstract: The present study is an endeavor to detect and identify the geomorphologic changes in the area surrounding the confluence of the Two Nile Rivers (The Blue and White Niles). In so doing the study is primarily concerned to show to what extend these changes are reflected on the geography of the area. The research is based on the visual interpretation of five aerial photographs of the confluence area covering a time span of circa forty five years from 1952 to 1996. Furthermore, the photo – interpretation is augmented with the visual and digital processing of a recently acquired satellite image depicting the confluence area (2002). Remotely Sensed Techniques and Geographic Information Systems facilitated the exercise of deciphering the observed changes. The outcome of the performed study demonstrated the gradual, but steady transformation of Tuti Island into a peninsular. Such a contention entails the migration of the two Niles confluence site to the north of the future peninsular, probably opposite to Bait Al Mal area in Omdurman Town. As a result the residential areas in Omdurman Town in the vicinity of the new Two Niles junction site will be prone to unprecedented and devastating floods. And the Main River Nile will change its course and will flow between Khartoum North and the newly formed Bait Al Mal – Abu Roaf Nile River Bank. The envisaged changes are very profound and demand rigorous scientific verification hence it is recommended that a multi – professional team should be assigned to carry out a follow up programme
