Abstract: Several navigation problems along Nile River have been recently monitored by the Hydraulics Research Institute "HRI". Some of them were caused by the sediment and flow regimes which are completely different from the conditions before the construction of High Aswan Dam. Whilst the difficulties for some others were created due to the improvement that occurred in the water use which reduced the discharge and consequently the flow depth. The present paper deals with some problems developed as a result of the increasing human activities which are currently taking place along the Nile River. Two of those problems and the solution recommended for each one are presented. The first one was solved by means of a hydrographic field survey and desk study. This problem deals with the river effect on the bridge piers which are being constructed at Quena. While the second one was solved by means of a fixed bed scale modelling technique and deals with the navigation bottle-neck caused by constructing a new bridge across the Nile River at El-Menya City.
