Why did the proposed Red Sea–Dead Sea Water Conveyance project involve pumping water instead of siphoning it? (lemmy.ml)

The surface of the Dead Sea is hundreds of meters below sea level so it seems like pumping would only be needed to prime a siphon and then it could keep flowing. What am I missing?

I am a pretend engineer, so take this with a grain of salt, but my guess is that because its very hard to perfectly airtight seal a pipe of that length, the siphon would be very hard to maintain.
