It  is known for its many oases, water fountains and a predominance of sand  dunes. Several geological studies conducted on Rub Al-Khali have  affirmed the existence of human settlements that lived near water  basins. Arrow heads found in those areas confirm the practice of  fishing, and that humans dwelt at the site continuously over the years.”He  said the kind of bounteous rainfall as a result of the Mekunu cyclone  has not been experienced in Rub Al-Khali for the past 30 years or more.  The water will permeate the sand and the groundwater slowly over the  years due to gravity.Al-Shanti pointed out that there are many  sand types in Rub Al-Khali that echo the identity of the place and the  history of the human settlements.The site is a world of secrets  buried under the sand. The studies also included probing the meteorites  that fell in Rub Al-Khali, the caves, the marshes and all available  geological factors. The Saudi government has not spared any effort to  explore and conduct possible studies in an attempt to discover its  secrets.In an interview with Al-Arabiya, geological expert Dr.  Abdullah Al-Amri said the water current in Rub Al-Khali is located in  geological formations in the southeastern part of the Arabian Peninsula.  It covers a very large area. All streams of water come from the Arabian  Shield and from the north of Saudi Arabia, from Wadi Al-Rummah and  several valleys.Rub Al-Khali comprises deep spring water which  is over 5,000 to 10,000 years old, called the non-renewable groundwater  or deep water.Al-Amri emphasized: “We conducted a study three  years ago to explore water resources in Rub Al-Khali. We found two types  of water, including water near the surface which in a short period of  time ends up evaporating, like the water that is currently present after  the recent cyclone. The other type of water is located in deep  geological formations that are 4 km deep below the surface of earth.  Rain is abundant in Rub Al-Khali in a location situated at 500  kilometers from the city of Harb.”He pointed out that  exploratory studies in Rub Al-Khali proved that the desert has immense  water resources, but a large proportion of existing water contains a  high amount of sulfur.In the past, it was believed that the Rub  Al-Khali is a running river, which was the common idea. Geophysical  studies have revealed deep waterways, some of them still exist to this  day while others perished.Some of the sites are rich in water, while others contain formations and layers of oil and gas.Water  presence becomes stronger in the southeastern border of Saudi Arabia,  the UAE and Oman, which are water-rich locations because of moist water  swales, since runoff water is inclined to flow according to the  different slopes that are inclined toward the easterly or southeasterly  direction.On the effects of the water left by the cyclone,  Al-Amri said: “At this point the water is lying on top of the ground and  it would take years for it to reach the underground. The water in Rub  Al-Khali is mostly formed during the ice age that covered the whole  world 10,000 years ago and which is now lying at the bottom of the sand  dunes.”Despite the harshness of the natural environment in this  region and the lack of human activity, it is rich in oil, natural gas,  radioactive metals, glass sand and solar energy. The experimental wells  drilled in the east and southeast of the desert of the Empty Quarter  shows that the water is abundant in the Eocene limestone formations,  which are similar to the water-bearing layers as in Al-Ahsa.</blockquote>
