Levantine Sea to be the oldest known ocean crust worldwide. The Suez Canal was completed in 1869, linking the Levantine Sea to the Red Sea. The Red Sea's level is higher than the Eastern Mediterranean, so the canal serves as a tidal strait that pours Red Sea water into the Mediterranean. The Bitter Lakes, which are hypersaline natural lakes that form part of the canal, blocked the migration of Red Sea species into the Mediterranean for many decades, but as the salinity of the lakes gradually equalized with that of the Red Sea, the barrier to migration was removed, and plants and
Mediterranean–Dead Sea Canal descent to the Dead Sea from where it will drop almost 400 m through a pressure shaft to drive three Francis turbines with an output of 100 MWe each. The sketch of the projected system illustrates the continuous supply of water from the Mediterranean sea (west to east) by a 7 km long free-surface flow channel, a 65 km long pressure tunnel and a 3 km long storage pool. This underground power station design is the world's first planned high-pressure seawater power station. The approx. 8 m diameter pressure tunnel is designed for a maximum flow rate of 2.5 m/s
