If a pipeline is developed to pump sea water into the desert, would that create a natural precipitation system and irrigate the surrounding land?

There was a project the British were considering back in the early 1900's called the Qattara Depression project. The idea was to create canals to allow water to flow downhill into a huge area of the Sahara that is below sea level. They would create an inland saltwater lake, and generate hydroelectricity along the canals. 

Fishing, transportation and water supply would be revolutionised and it would bring industry to some of the poorest parts of the world. Eventually the lake would turn hypersaline due to evaporation but it would last for a while. It was also believed it would improve the climate of Europe, and turn the surrounding areas into Savannah.
