摘要

The old irrigation hydraulic structures along the Nile and its main branches face the problems of operation, aging, ill maintenance and the desire to extend its lifetime. Economically, building a new one is not feasible. Furthermore, the operation of the irrigation system changed dramatically after building the High Aswan Dam and new design codes replaced the old design methods. Upgrading and enhancing old masonry hydraulic structures in Egypt is an extreme necessity and traditional solutions are not compatible with the operational requirements. For a reason or another, several structures such as Assuit and Zefta barrages have been remodeled. Upgrading and renovating constitute several studies and structural solutions that are not commonly available and has to be taken as a case by case matter, and the literature does not support such cases well.This paper presents several upgrading solutions for an old regulator, where not all methods are convenient. A study of the different methods is presented and analyzed.
