أسرار البرزخ المائي بين الماء العذب والماء المالح

---

this verse that the sea could be tortured Vrata can be urgent was brine. In this verse a reference to the presence of a solid barrier and strong he called the Quran (the isthmus).

Those who ponder this verse that God is aware of talk about a great miracle and a great mandate, the intermingling of fresh water salt water through a solid barrier and the stone well. And if God gives us an indication of the importance of this region, any region of the mouths of rivers in the sea, and this is what see now scientifically.

What is the stone?

Turquoise Abadi says the dictionary, the lexicon: "the stone: prevention, and grew up in a room, namely: to keep the" [1]. We can conclude that there is a kind of barrier and preserved the auspices of God, or that there is an area of water surrounded by barriers like a closed room, says Ibn Kathir in his interpretation of this verse: "Bahrain is the prairie: the creation of Almein, sweet and salt. Vahalo Kalonhar and eyes and wells, This is the sweet sea. and make them Brzacha: any barrier, and a stone Mahjura: any object that the one to the other [2]. " But what about modern science and what to say to this?

The importance of the isthmus of water

Isthmus of water is an area on the mouths of rivers where the river meets the sea, that is, when fresh water meets salt water, a region that is the barrier closed and surrounded by water or land. Scientists today call the estuary and these areas are of keen interest to scientists, because the fresh water miscible Balmalh phenomenon is unique and truly remarkable [3].

The visiting this area of the mouth, or call the Koran or the isthmus region of the barrier noted significant differences in the environment and the differences in the intensity and the degree of water salinity and temperature of the moment to another and from one chapter to another [4], that there is any process of mixing and blending and overlapping of continuous fresh water and salt water .

And perhaps wonder if we know that the word (Marj) in says: (which has a plain Bahrain) accurately reflect the operations in this region and the newly allocated by the scientists.

In the dictionary, we find the meaning of the word (Marj): confusion, and ordered alloy: a mixed, and the Lawn: mixing and turbulence [5]. In the interpretation of Ibn Kathir: "Amartij: different ambiguous evil troubled him, Kcolh meaning (according to you is in the various) [Almariaat: 8]" [6].

And very strange that what is happening already in the area of the mouth includes all these meanings, namely, that the word Quran accurately reflect the reality of what is happening, how does not reflect the reality of the status of the creator of this pipe Almighty?

Downstream sections of the region

Scientists today divide the downstream region into three sections:

1 - the area of fresh water on the river.
2 - the area of salt water from the sea.
3 - the area of the barrier between the river and the sea, which is what he calls the Koran the isthmus.

And could extend the influence of freshwater salt water for hundreds of kilometers into the sea. Although there are many of the estuaries in the world, but there is no other like the Isthmus! All the isthmus is characterized by specific characteristics of the other tracking the difference in the degree of salinity, and the differences in temperature, and this is followed by the degree of salinity of sea water, and the length of the river, and other factors such as the degree of acidity and PH plankton in water quantity and speed of the flow of river water, the river ... [7 .]




Satellite image of the NASA of the mouth of the "Rio de la Plata" in Argentina, shows the area of the isthmus and a clear color and distinctive characteristics [8].
The classified

In the estuary, where the river meets the sea, this region is characterized by the presence of a significant difference in the degree of salinity, temperature, and in spite of that there are organisms and plants and animals adapted to live in this region.

The organisms that live in salt water can not live in fresh water, because the body cells contain the specific focus of the salt, once the dumping of fresh water will die because of the entry of fresh water to the body in large quantities.

Organisms that live in fresh water also can not live in salt water for the same reason, and the organisms that live in the region between the river and the sea of any of the isthmus, it also can not live outside this region because they adapted it and, therefore, exists today scientists studying the region downstream as an independent nature and its laws, Kainadtha.

This indicates that the downstream area is classified and have independence and also reserved the auspices of God, which is a closed area like a closed room, can thus be understood in greater depth the meaning of the words the meaning (and make them Brzacha stone Mahjura).




There are many organisms that live in the area of the estuary between the river and the sea, God has provided them with can cope with the large differences in temperature and salinity in the region. These fish adapted to the continuing difference in the degree of salinity, temperature, and these organisms can not live only in this region, and the area of the isthmus, and are classified this and prevent the entry of any of the other organisms.
Mixing and turbulence and the different

The greatness of the Quranic statement that gives us the precise expression of scientific and concise in the least number of words, word (Marj) contains many of the most important meanings:

1 - confusion: Scientists say that there was confusion and a constant mixture of salt water with fresh water, and this confusion does not stop ever, since the surface of the water rises and falls constantly and the system of an arbitrator, and the water remain separate from each other a specific region between the two is what the Koran called the isthmus, the isthmus has extends for several kilometers. It is the meaning of the word (Marj): confusion, as we have seen.




We believe in this form Alfraser River, which originates from Colombia and was in the salty ocean water. And see how the front shape, which is salty and served as an arbitrator with which the fresh water to salt water. We also see how the fresh water floats on the surface of salt water, when the scientists studied the flow of water in this region and found Jriana disturbed, knowing that the water that looks at the finger think, and this is fully consistent with the Almighty as saying (the Marj al-Bahrain), The Lawn is the turmoil, the Glory know the secret and concealed!
2 - turbulence: If we look at the note that the region downstream run stable, it is often a quiet place. But the new tests in the area of the isthmus between the river of fresh water and sea salt indicated that the turbulent flow is run, and this information is not accurate to the scientists only recently [9]. This is one of the meanings of the word (Marj).



, researchers are taking samples of water and deposits of the isthmus between the river and the sea (downstream region), these scientists have found that there is a continuing mixture of salt water with fresh water, and found significant differences in the rate of salinity, temperature and density from one region to another and from time to time, They also found that the water flowing beneath the surface of a troubled, knowing that the eye appears to be stable, then found the three realities in the region: the disorder run, and the mixing of the water constantly, and the different characteristics of water, and collected the three meanings of this word is one (Marj), Glory to God !
3 - the difference: there is a difference in temperature and salinity according to night and day, is a meandering curved black tide, ie, a high level of surface water and a decline between day and night, the red line represents the temperature difference between day and night, while the blue line represents the difference between the degree of salinity night and day. Of course, when the rising sea level, the degree of salinity of water increased in the region of the isthmus, while when the sea is in the case of islands, the amount of fresh water flowing from the river increased, and thus the salinity of water in the mouth.

It should be noted that the difference in the degree of salinity followed night and day, month and chapter, and the temperature and the movement of tides. And perhaps remember says: (in the creation of the heavens and the earth and the alternation of night and day are signs for men of understanding) [Al-Imran: 190]. In this verse a reference to the kind of differences and the many changes that we see during the day and night, including differences in temperature and salinity in the area of the isthmus. The word (Marj) this effect.



تعتبر منطقة مصبات الأنهار في البحار من أجمل المناطق وأكثرها غنى وقد نشأت كثير من الحضارات حولها، ومنطقة المصب تكون عادة محاطة بالغابات والنباتات المنوعة من أطرافها الثلاثة ومفتوحة على البحر حيث يختلط الماء العذب بالماء المالح. إن منطقة المصبات لها خصائص وميزات رائعة، فكل شيء في هذه البيئة المميزة يختلف عما يحيط بها، فهي بيئة محفوظة ومحجورة وممنوعة من أي كائنات حية أخرى غير الكائنات التي تعودت على العيش فيها، ولها خصائص فيزيائية وكيميائية أيضاً تتميز بها عن غيرها من المناطق.
مياه عذبة في قاع البحر!
لقد اكتشف العلماء وجود ينابيع عذبة تتدفق داخل المحيطات والبحار مصدرها المياه الجوفية المختزنة في طبقات الأرض. ويمكن القول بأن عملية امتزاج الماء المالح بالماء العذب لا تقتصر على الأنهار بل هنالك مياه مخزنة تحت الأرض أيضاً تتدفق وتمتزج بمياه البحر، ويحدث اختلاط واضطراب واختلاف في درجات الملوحة والحرارة، وبالتالي فإن التعبير القرآني (مرج البحرين) ينطبق على هذه الحالة.

وتبلغ كمية الماء العذب المختزن تحت الأرض كمياه جوفية 23.4 مليون كيلو متر مكعب، بينما تبلغ كمية الماء الموجودة في جميع الأنهار في العالم 2.12 ألف كيلو متر مكعب فقط، ويبلغ حجم الماء في البحيرات العذبة 91 ألف كيلو متر مكعب، ويمكن القول بأن حجم الماء المختزن تحت سطح الأرض أكبر من حجم الماء في الأنهار بـ 250 ضعفاً[13].

رسم يوضح دورة امتزاج الماء العذب بالماء المالح، فالأنهار والينابيع والمياه الجوفية تشارك في هذه العملية مع ماء البحر، ولذلك نجد البيان الإلهي يعبر تعبيراً دقيقاً (مرج البحرين هذا عذب فرات وهذا ملح أجاج)، وفي تفسير ابن كثير كما رأينا فإن البحر العذب هو الأنهار والآبار أو المياه الجوفية والينابيع، وجميع هذه المياه تمتزج وتختلط بماء البحر، فانظر إلى دقة كلام الله تعالى[14]!
