It used to happen naturally with the Nile's seasonal floods; after the completion of Egypt's High Dam in 1970 (one of the most ambitious engineering projects on earth), these seasonal floods came to an end, but a vast network of irrigation canals continued to bring gallons of freshwater to the people who worked the land, the fellahin , ensuring salinity levels remained low.

过去，这一使命自然而然地要由尼罗河的季节性洪水来完成。但是，1970年后，埃及大水坝的竣工（世界上最宏伟的工程项目之一）为这种季节性洪水划上了句号。但是，巨大的灌溉网络继续将大量的淡水送到在田间工作的人--农民的身边，从而使土壤盐度仍然维持在低水平上。
