The scientists have studied the downstream area of the river into the sea, they found that this area has specific characteristics as it is moderate in salinity and density while at both ends we find a sweet river (palatable and sweet) and a sea with excess salinity (salt and bitter). And this downstream area is ecologically very sensitive and it works on isolating the sea from the river otherwise the salty water will mix with fresh water and all the rivers in the world will be spoiled.
Through this scientific fact, it is shown that this region that separates the sweet river from the salty sea is a very important region and it has different characteristics than that of both seas (the sweet and the salty). Scientists have found also that it has specific creatures that live only in it like some kinds of fish.
The Quran talked about this grace (a barrier and a complete partition between them) which means the forbidden area from the tyranny of the sea and it is one of the miracles of the holy Quran. So we have to thank God for this grace. God be he exalted says:
(And it is He Who has let free the two seas (kinds of water): this is palatable and sweet, and that is salt and bitter; and He has set a barrier and a complete partition between them.)
[Surat Al-Furqan, verse: 53]
