Development of a FoxPro ArcInfo System for Navigation Bottleneck Identification in the River Nile
This paper is aimed at the development of a FoxPro ArcInfo system that makes use of historical data of the Nile River to identify potential locations of navigation bottlenecks in the Nile downstream of the Aswan High Dam. During the development of this system, two different modules were developed to perform three different tasks. The first module was developed to handle data input and output for the historical data that are available at the Nile Research Institute (NRI). This module was developed using database management information system technology and FoxPro 2.5 under Windows software to be able to handle such huge amounts of data. The module includes a water surface profile calculation that corresponds to certain water management parameters (discharges and water levels). The second module was developed for three-dimensional GIS analysis using ArcInfo SML and ARC TIN modules. The system output includes thematic maps resulting from three-dimensional analysis to provide the necessary information
about bed and water levels, and in particular the potential locations of navigation bottlenecks that correspond to the calculated water surface profile. As an application of the system, two case studies at Sharona, just upstream of Maghagha City, and at El-Zawya, just upstream from Menia City, were conducted. These sites are suffering from navigational bottlenecks as there are many submerged islands. The system application at these sites includes the input of the newly surveyed cross sections. The system output are contour maps for both bed elevations and depths. It also includes the potential location of the navigational bottlenecks. The system output includes the volume of dredging if desired.
