Abstract

In today's world, river transportation is one of the most significant tasks. Due to physical changes, navigation bottlenecks arise along the river. Furthermore, any building erected on the river, such as bridges, might alter the river regime, potentially causing local navigation bottlenecks. The goal of this study was to look into the morphological changes caused by the El-Menia Bridge. The current paper examines the Nile River's grain size distribution pattern. The goal of this research is to look at the suspended load and bed load of the study region before figuring out the best way to solve this navigational issue. The purpose of this investigation, however, was to highlight the existing sediment quantity. According to the study, the velocity and total suspended load on the west side are higher than on the east side. Dredging is the best solution for the El-Menia Bridge's navigation problems since it raises the bed level on the east side of the river channel, where the bridge's major navigation vent is located. Bottlenecks in the navigation system have appeared, and a traditional approach has been implemented to fix the problem.
