SAFE NAVIGATION ON THE NILE RIVER TEAM (6) MEMBERS AHMED YASSER AHMED MOHAMED NASSAR HOSSAM HASSAN RAMADAN HASSAN AHMED FAYEZ MOHAMED AHMED AHMED MOHAMED MESBAH ELSAYED AHMED ABDEL-RAHMAN GALAL ABSTRACT Millions of tons of cargo is transported over the Nile River yearly. Hundreds of Nile Cruises (Floating Hotels)operating between Luxor and Aswan. the Egyptian government gives a high priority to the improvement of safety of navigation on the Nile River. Cargo Ship Nile Cruise INTRODUCTION Transport on Nile River is for: Goods and Materials Tourists and Passengers INTRODUCTION SAFE VISUAL NAVIGATION implementation of hydrographic survey. cost effective solar-powered visual aids to navigation. Together with further development of infrastructure works along the Nile River. vessel tracking system for Nile cruise ships for lock passage planning and emergency cases. PROBLEMS OF Long duration of transport due to daylight navigation only NAVIGATION LOW FLOW OF CARGO REASONS: Unreliability of the river; no technical means for safe navigation in the navigable channel. Poor quality of services Unreliable delivery times due to grounding or technical failures of the barges. Poor quality of barges. AIM Is to define and design the main steps that should be followed now and, in the future, to achieve safe visual navigation on the Nile River. Considering (IHO) standards for hydrographic survey. HYDROGRAPHIC DATA ACQUISITION Data ACQUISITION Water level records Data Collection Vertical Position Horizontal Position Data Logging Data Processing Shoreline Survey Ortho-photos-Coordinates of First Order Points DATA ACQUISITION WATER LEVEL RECORDS Ministry of Public Works and Water Resources maintains a series of Staff Gauges along the Nile River from Aswan to the Mediterranean Sea. . The MPWWR can provide the water level reading daily. Overall, station readings are sufficient for the need of hydrographic survey. DATA ACQUISITION WATER LEVEL RECORDS Tide Guage DATA ACQUISITION VERTICAL (DEPTH) POSITION The flow depth is recorded referring to the bed level. The output data in form of chart . The output depth in the form of digital data is logged into data logger. DATA ACQUISITION HORIZONTAL POSITION boats are equipped with GPS antenna and controller. A reference installed GPS station is over a defined controlling point. Momentarily, The corrected horizontal position is logged into data logger to be integrated with vertical position. DATA ACQUISITION DATA LOGGING Data from DGPS system and digital depths from Echo sounder are logged in an ISAH data logging system (Integrated System for Hydrography). Automated DATA PROCESSING Sounding and position data are saved then processed workstation. then depths and positions are plotted on the screen and erroneous data are rejected. To produce navigation charts, depths were set to the chart datum .
