Sehel Island Sehel Island Sehel Island is located in the Nile, about southwest of Aswan in southern Egypt. It is a large island, and is roughly halfway between the city and the upstream Aswan Low Dam. Sehel Island, spanning 3/4 the width of the Nile, is the primary large island below the Nile's First Cataract and the Aswan Low Dam (1902). Following downriver, the next major islands after Sehel are: Saluga, Ambunarti, Elephantine, and then Kitchener's Island. There are a dozen smaller islands scattered around them. The island was known in ancient tiles as "Setet", and there are many archaeological sites, including
Aswan Dam soil surface over the years. Since most of the farmland did not have proper subsurface drainage to lower the groundwater table, salinization gradually affected crop yields. Drainage through sub-surface drains and drainage channels is essential to prevent a deterioration of crop yields from soil salinization and waterlogging. By 2003, more than 2.0 million have been equipped with a subsurface drainage system at a cost from 1973 to 2002 of about $3.1 billion. Contrary to many predictions made prior to the Aswan High Dam construction and publications that followed, that the prevalence of schistosomiasis (bilharzia) would increase, it did not. This
