The aim of this study is to evaluate the effect of hydraulic structure components arrangement on inland navigation. The study was mathematically carried out by applying the SMS 2-D (Depth average) numerical model representing an 6.0km straight reach symbolizing main River Nile characteristics. To identify the hydraulic and morphological features of the representative river reach, an introductory study was conducted comprising each of the main River Nile stream and each of Damietta and Rosetta branches. Therefore, the most up-to-date design specifications and techniques were applied to design the multiple function hydraulic structure components (such as gated sluiceway; hydropower plant; double navigation lock chambers; and closure dam) that related to the existing River Nile circumstances. Consequently, the induced transverse velocity components downstream the multiple functions hydraulic structure components -Corresponding to different flow conditions- were examined in view point of safe inland navigation. Three tests were applied; the first two basic and applied testing programs represented an ideal reach signifying the typical characteristic of River Nile reach, while the third validity testing program represented an actual river reach of Assiut barrages. Evaluation of the attainable results revealed that the most efficient and optimum hydraulic structure components arrangement is fulfilled when the navigation lock is located on the eastern river followed by the hydropower plant; gated sluiceway; then the closure dam. While testing the new Assuit barrages led to conclude that the selected design would not be technically feasible and efficient to satisfy safe inland navigation.
