The great importance of the Nile River emerges not only from the fact that it represents the main water source for Egypt but also from its being an important water path for sailing either to transport goods or for Nile tourism cruises. this study aims at developing user-friendly web Google Maps that introduces the locations of bottlenecks that threaten navigation safety in the first reach of the Nile, which extends from Aswan Old Dam (AOD) to Esna Barrage for about 167 km. The location of bottlenecks is variable based on the Nile Riverbed morphology and the real-time water level. AutoCAD Civil 3d is adopted to obtain these locations and also export bottlenecks locations map based on the topographic and hydrological data, as well as the alignment and geometry of the navigational channel. A quasi-real-time model for the navigational channel was created based on minimum water levels at the winter closure of Aswan High Dam. Two surfaces were created: the bed surface and the navigational channel surface using a Triangular Irregular Network (TIN). In addition, the tin surface volume was created from the comparison between the previous two surfaces. Both longitudinal and cross-sections along the locations of the bottlenecks were obtained. Findings from the current work revealed that 2,244,090 m3 of sediment should be dredged. moreover, this study provides a simple solution for avoiding the bottleneck areas online by exporting the bottlenecks river map to Google Maps.
