According to the Floating Hotel Association of Egypt, a total number of 310 floating hotels were in operation in the Nile River between Luxor and Aswan in year 2006. This cruise route of 223 km destination is suffering high traffic densities, vulnerability to hazard accidents, and not able to secure safe journeys. Also the current cruising program is causing a shortage in the number of berthing units. Consequently, several aground accidents at different locations were recently documented during the top tourist season of year 2017. On the other hand, the number of floating hotels was linearly enlarged at a rate of 10 units a year, which will make the projected number of tourist hotels in 2025 around 499 units. With such rate of increase, the number of expected accidents and aground coincidences will be doubled, while parallel docking for several rows despoils the tourists' privacy as the berthing units would be very close to each other. To face such circumstances, the number of expected cruising programs was hypothetically increased in the present study by adding various possible tourist routs along the Nile River. Accordingly, the average rout length would be indirectly increased and the tourist barges would be dispersed along a lengthier stretch of the river. The objective of the current study is to examine the impact of increasing the number of cruising programs on improving the safety and working efficiency of floating hotels navigation. The present study proposed five additional cruising programs that would take place between Aswan and Cairo with a minimum and maximum cruising rout of 118.3 km and 928 km respectively. A significant reduction in docking shortage between Aswan and Luxor was achieved over the present cruising program. The study revealed that applying the innovated scheme in year 2025 will tremendously reduce the number of docking units and consequently the docking lengths in Aswan and Luxor to 64.5 % and 83.8 % of the existing condition respectively. Also the proposed scheme will lead to reduce the needed docking length between Aswan and Luxor in year 2025 to 30.6 % of the existing condition. Our findings show that the floating hotel cruises should be extended to cover several attractive sites that distributed along the Nile River between Aswan and Cairo. less

Accurate determination of flow discharges passing through streams or rivers is essential as it ensures good quality of dependant hydrologic or hydraulic studies. So many hydrological research works have addressed the Blue Nile system in various aspects. However, the river reach in Sudan (~ 700 km) lacks detailed studies for its hydrological network. Khartoum is one of the important gauging sites on the Blue Nile in Sudan. It controls the total yield of the Blue Nile before it joins the White Nile to form the Main Nile which flows downstream to Egypt. During flood time, close observation of the flood levels at the Sudanese capital Khartoum is very vital and it is highly linked with observed water levels at Eddeim on the Ethiopian/Sudanese border. Historically, the record at this site has started since 1904 and is a combination of flows from two sites: high flows are measured at Khartoum itself, while low flows are measured at Soba which is about 25 km upstream. In fact, Khartoum can reflect the total yield of the Blue Nile at Eddeim, which represents over the years a very good control to the yield from the Ethiopian Plateau, taking into consideration the lateral flows as represented by the contribution of Dinder and Rahad Rivers and the total irrigation abstractions along the Blue Nile reach besides the probable conveyance and evaporation losses. This work highlights the performance of the major gauging sites on the Blue Nile with special emphasize on Khartoum station to deliver accurate flow discharges. Based on in depth investigation of water levels/flows at Khartoum for about fifty-one years (1965-2015) and simulation of flow records using RIBASIM software besides water balance computations with neighbouring sites, concrete conclusions are derived on the performance of Khartoum station. In general, it was concluded that the gauging stations at downstream Roseires and Sennar dams are of good performance. For Khartoum station, it was found from water balance computations that the observed annual yields were overestimated by 6% over the period of investigation. Using RIBASIM simulations on 10-day time step, it was found that the observed flows were underestimated by about 9% and were overestimated by about 8% versus simulated flows in years of low and high flows, respectively. Hence, the reliability of the flows at Khartoum are limited and their accuracy is subjected to the quality of ratings and the lack of discharge measurements throughout the year. Key words: Blue Nile in Sudan, Khartoum gauging site, discharge reliability less
