A representative design ship was chosen for studying the effect of cross water currents on navigational ships based on statistical analysis of the available data for ship units along the River Nile, Egypt. A geometrical wooden ship model of a design representative prototype was tested in a rectangular flume at the Hydraulics Research Institute (HRI). The aim of this study is to provide operational traffic safety for passing ships along the River Nile, Egypt and to accomplish suitable designs of outfall structures, the proper design of guide pier downstream barrage components, or to verify the safe navigable path through bends.
