【 摘 要 】

In recent years there are needs to initiate the efforts towards developing evaluation tool for the navigation condition of the existing berths on the Nile River. Main goals of the research are to develop GIS application for the berths data and link it to a numerical model for evaluate morphological and hydraulically changes at the berthing area. The established application is used to evaluate the existing berths conditions at Luxor reach. The investigation included the physical, hydraulic, morphological, navigation conditions for safe and reliable navigation operation. The model was applied to create base flow map for morphological and hydraulically changes at the berthing areas. It was indicated that the rate of deposition is much more than the rate of erosion. It is concluded that the percentage of 26% of the existing berths are satisfied the navigation depths conditions, the percentage of 58% require maintained dredging and the percentage of 16% of the existing berths does not satisfy the navigation depths conditions. The developed evaluation tool is essential for improving and the rehabilitation the navigation conditions of the existing berths.
