The Qur'an speaks about the due measure of water

I started to study hydrology during my first years of study in university; I stopped many times to think in the complication of that science. It took long time from the scientists to discover the physics rules concerning that science, but there are some vagueness concerning many questions about that science.
I studied many theories in that field. But I didn't imagine that I may find these scientific facts in a book which was released from hundreds of years! I read researches for scientists who started their studies at the beginning of the twenty century when they got the scientific tools and the Laboratory analysis; they used to stay in their laboratories for many years to get a single scientific fact about water.
Therefore, discovering the rules which control movement of fluids is considered to be a huge jump in understanding the water around us, any one who think in these rules must say "Glory to Allah" who says
( The Work of Allah, Who perfected all things, verily He is Well-Acquainted with what you do.)
(Sûrat An-Naml-verse 88).
God be He blessed and exalted put the physic rules in the water to be evidence that creation of God is precise, and to believe in the grandeur of the God.

According to the modern science for fluids especially the water, the scientists confirm that the water is revolving a precise and accurate circle. And there are physical rules to control every drop of water starting from the time of the descending from the sky till it reaches us. All stages are in precision not at random.
If we look attentively, we can see a precise system which testifies that the creator is great, also we see fixed physical rules as an indication for an organizer who knows everything (God be He blessed and exalted). God says
:( Everything with Him is in (due) proportion *All-Knower of the Unseen and the seen, the Most Great, the Most High.)
(Sûrat Ar-Ra‘d- verse 8-9).
Here we can see the koranic miracle as God says :
:( And who sends down water (rain) from the sky in due measure)
(Sûrat AZ-Zukhruf- verse 11)
hence we can see how God be He exalted made a link between sending water from the sky and the word (in due measure) which means a precise and calculated system.
The one drop of water contains five thousand million of molecules!!! God had organized this precise system in a due measure. God says
:( And we sent down from the sky water (rain) in (due) measure)
(Sûrat Al-Mu’minûn- verse 18)
which means in a calculated and precise system. That is the same as what the scientists tell us about the precise and accurate system of hydrology on earth.
God be He exalted had mentioned the water in the Qur'an in many verses such as:

1. The Qur'an told us about these huge water tanks which are under the ground of the earth which are more than the sweet water in the rivers, God says:
:( and it is not you who are the owners of its stores [i.e. to give water to whom you like or to withhold it from whom you like].)
(Sûrat A-Hijr- verse 22)
this sentence refers to the operation of storing the water, as this information was unknown by anyone at the time of the Qur'an.
2. The Qur'an told us about the long time that the water stay in the ground without spoiling , God says:
( and We gave it lodging in the earth)
( Sûrat Al-Mu’minûn- verse18).
In this sentence a sign that the water stays for a long time in the ground(Lodge) despite the existed impurities materials, Microorganisms, fungi, salts and minerals underground but the water stay clean and pure. That is Allah who put the rules to do all of that.
3. The Qur'an told us about the role of the mountains in purifying the water , this information was unknown by anyone at the time of the descending of the Qur'an , as the taller the mountains the purer the water. God says :
( And have placed therein firm, and tall mountains, and have given you to drink sweet water?)
( Sûrat Al-Mursalât- verse 27).
4. The Qur'an told us about the calculated and precise operations which control the descending of water and its cycle, God says:
(And who sends down water (rain) from the sky in due measure) (Sûrat AZ-Zukhruf- verse 11).
Finally my dear reader, don't you see that the Qur'an spoke about everything? God says
:( And we have sent down to you the Book (the Qur’an) as an exposition of everything, guidance, a mercy, and glad tidings for those who have submitted themselves (to Allah as Muslims).)(Sûrat An-Nahl-verse 89).
