  Qattara Depression
The Qattara Depression (local: Munkhafad al-Qattarah) is a desert basin within the Libyan Desert of north-western Egypt.
The Depression covers about 18,130 km² (~7,000 square miles), and at its maximum is 80km in length and 120km in width.
The bottom of the depression consists of a salt bog.

  Qattara Depression - Wikipedia, the free encyclopedia
The Depression is an important habitat for the Cheetah, with the largest number of recent sightings being in areas in the northern, western, and northwestern part of the Qattara Depression, including the highly isolated, wild oases of Ein EI Qattara and Ein EI Ghazzalat, and numerous Acacia groves both inside and outside the depression.
However the Depression is inhabited by the nomadic Bedouin people and their flocks, with the Moghra oasis being important in times of water scarcity and dry seasons.
The area is composed of sand dunes and salt lakes in a tear drop shaped formation with the point of the drop facing east and the broad deep area at the south west end.

However the Depression is inhabited by the nomadic (A member of a nomadic tribe of Arabs) Bedouin people and their flocks, with the Moghra oasis being important in times of water scarcity and dry seasons.
Because the depression is so deep and broad a great deal of water would be let in to maintain the artificial salt sea at the 300 foot level and as the water evaporates more sea water would be sent through the penstocks to generate more electricity.

 Libyan Desert - Wikipedia, the free encyclopedia
There are eight important depressions in the Libyan Desert, and all are considered oases except the smallest, Qattara, because its waters are salty.
The Qattara Depression, which contains the second lowest point in Africa, is approximately 15,000 square km (about the size of Connecticut and Rhode Island), and is largely below sea level (its lowest point is 133 meters below sea level).
The sparsely inhabited Qattara Depression is covered by badlands, salt marshes and salt lakes.

Qattara Depression, desert basin in the north-eastern Sahara, north-western Egypt.
The Sahara as a whole is a raised tableland with an average elevation from about 395 to 490 m (1,300 to 1,600 ft).
Very large depressions may, in some cases, be partly tectonic in origin but deflation is an important process in their formation.

The Libyan or El-Diffa Plateau in north-western Egypt extends from the Libyan border to the Qattara Depression, north of 29 N, reaching a height of 215 m a.s.l..
All of these depressions have been formed by wind erosion and are termed deflation hollows; the areas of weaker rock in the Nubian sandstone sequence are preferentially eroded.
For instance, the Qattara and Siwa Depressions are formed along the same structural trend; the Bahariya and Farafra Depressions, and the farafra, Dakhla, and Kharga Depressions, form other structurally related groups.

 Managing water for peace in the Middle East
This particular type of hydroelectric project, generally known as solarhydro, would be made possible by the combination of such factors as the existence of a vast depression at a distance not too far from the sea in a region with characteristically scarce rainfall and a resulting high degree of evaporation.
The Qattara depression is located in the north-western part of Egypt and is the world's fifth deepest natural depression.
The utilization of the Qattara depression to develop hydroelectric power was first suggested by the Berlin geographer Professor Penk in 1912, and later by Dr. Ball in 1927.

When the Germans closed off the LRDG route that followed the northern rim of the Qattara Depression, the SAS was forced to explore what was considered an "impassable" path through the Depression itself.
The Depression, which was shaped something like a cutlet, was 150 miles in length and 75 miles across at the widest point.
It was therefore important to cross the basin either at night or during the midday heat haze.

 Qara Oasis and the Qattara Depression, Egypt. Travel guide & tourist information by Hostelbookers.com
Northeast of Qara the land plummets into the Qattara Depression, which is seven times the size of all the Western Desert oases combined and may be the largest depression in the world.
There is, however, exploration for oil at many points in the desert between Qattara and Mersa Matrouh, which explains the upgraded tracks that crisscross the wilderness.
While crossing the depression, it passes the uninhabited Maghra Oasis, where Jurassic fossils of mastadons, reptiles, fish and mammals have been found; petrified wood lies around, and there's a salt lake.

The sedimentary and early diagenetic features of the evaporite deposits of the floor of the Qattara Depression have been investigated by field and petrographic studies in order to develop a depositional model in the light of the present day climatic data and geographic setting.
Most of the floor of the depression is occupied by recent salt flats (sabkhas) which are dominated by thick and thin halite and gypsum crusts.
The existence of halite and gypsum in the recent salt flats and gypsum/anhydrite in the Quaternary evaporite hills point to a long arid episode over the depression, with either differences in the composition of the parent brine or relative humidity and evaporation rate.

The Siwa Depression in Egypt is much smaller; it extends in an east-west direction with a length of 80 km and maximum breadth of 26 km.
Moreover, there is a proposed project to flood the Qattara Depression with seawater to make an inland sea that would destroy the natural habitats and replace them with a large salt lake.

Also visible in the image are brown and greenish areas to the west of the clouds (near the Libyan border) that are associated with the Siwa Oasis.

The depression continues in a shallower form west, to the oases of Jaghbub and Jalo in libya.
The huge volume of sand excavated by the wind from the Quattara and other lesser depressions have been organised into a huge area of parallel sand dunes, hundreds of kilometres in length, and occasionally reaching heights of a hundred metres.

The sabkhas of the Qattara Depression are considered a terra incognita.
The modern estimate of seepage water into the depression is equivalent to the total evaporation of the water from the sabkhas.
The origin of these waters is considered to be partly rain-water and mainly ground-water from the Moghra aquifer in eastern Qattara and ground -water from the Nubian Sandstone in western Qattara.

 Qattara Depression, Egypt
The Qattara Depression, the largest and most northerly of the Egyptian oasis depressions, is a deep wide rift in the gently undulating plateau of the Western (Libyan) Desert, lying within the triangle formed by El-Alamein, Mersa Matruh and the Siwa Oasis.
The depression, filled with impassable and treacherous salt swamps (sebkha), is some 175mi/280km long and up to 90mi/140km wide, with a total area of some 6,950 sq.
With a difference in level of some 177ft/54m when the basin was full it would then be possible to harness the water for the production of electric power and perhaps also to operate a plant for the desalination of sea water.

The gap between Fortress A and the Qattara Depression became the responsibility of mobile columns of 7 Armoured Division.
The Qattara Depression itself, a perpetual and practically impassable obstacle that precluded any possibility of a serious outflanking threat in the south, is a wide expanse of salt marshes about 7000 square miles in area.
