the Aswan Low Dam or the old Aswan Dam could be a masonry-contrafort dam on the Nile in the Aswan of Egypt. The dam was designed at the previous initial cataract of the Nile and is found regarding a thousand metric linear units up-river and 690 metric linear units east of Cairo.
The Low Dam in Assouan was equally spectacular once it had been initially designed by land at the tip of the nineteenth century nothing of its scale had ever been tried before. whereas it worked with success for several years, it did not meet the nation's growing desires, and also the levee was so designed.
this wasn't the primary plan to dam the Nile. The earliest record of plans for a dam is from the eleventh century. Ordered by Fatimid Muhammedan religious leader to manage the Nile's flooding, the engineer mathematician was terrified once deciding that it wasn't potential to try to do this, and insincere madness to avoid the Caliph's anger!
Once a contemporary marvel of the traditional world, Egypt's recent High Dam is currently nearly a century recent.
The High Dam
Once considerations regarding the structural integrity and unstable stability of the one,950-m-long, straight-gravity buttress dam surfaced within the early Eighties, the national High and Assouan Dams Authority conducted an intensive medical. As a part of the study, a team of researchers examined the condition of the masonry, conducted petrographic and chemical analyses, and determined the physical and mechanical properties of the dam's materials. it absolutely was found that original construction defects on the twice-heightened dam, like open-bleed water channels, moderate to severe honeycombs, and medium to giant cavities, had created the masonry permeable to the Nile's water from the get-go, that eventually junction rectifier to deterioration. Over the years, river water leaky through the dam enlarged the defects through chemical attacks and mechanical action and contributed to excessive consistency in some areas. However, tests that measure compressive strength, modulus of snap, shear strength, enduringness, relative density, and water absorption showed that the dam's masonry continues to be in comparatively fine condition.
