Nile River Valley and Faiyum Oasis, Egypt

Egypt - January 5th, 2012

The northern section of the Nile River flows almost entirely through desert, from Sudan into Egypt. Most of the population and cities of Egypt lie along those parts of the Nile Valley north of Aswan. The valley can be observed here, appearing as a thick green band on either side of the river as it flows through the Sahara Desert.

The Nile ends in a large delta that empties into the Mediterranean Sea, which is partially visible at the top of the full image. The other green area at the top of the thumbnail image is the Faiyum Oasis, a depression or basin in the desert immediately to the west of the Nile south of Cairo. The extent of the basin area is estimated at between 490 mi² (1,270 km²) and 656 mi² (1700 km²). The basin floor comprises fields watered by a channel of the Nile, the Bahr Yussef, as it drains into a desert depression to the west of the Nile Valley.

The thick green band running vertically through the center of this image is fertile land along the banks of the Nile River, in Egypt. Upon opening the full image, the Nile itself can be seen as a thinner, dark blue ribbon towards the right edge of the green land.

Branching off to the west is a heart-shaped area of green land known as the Faiyum Oasis. It is a depression or basin in the desert immediately to the west of the Nile south of Cairo. The extent of the basin area is estimated at between 490 mi² (1,270 km²) and 656 mi² (1700 km²). Over 400 mile² (1,000 km²) of the Faiyum Oasis is cultivated, the chief crops being cereals and cotton.

The basin floor comprises fields watered by a channel of the Nile, the Bahr Yussef, as it drains into a desert depression to the west of the Nile Valley. The Bahr Yussef veers west through a narrow neck of land north of Ihnasya; it then branches out, providing rich agricultural land in the Faiyum basin, draining into the large saltwater Lake Moeris (Birket Qarun), visible as a blue area at the upper limits of the green land.

Differing from typical oases, whose fertility depends on water obtained from springs, the cultivated land in the Faiyum is formed of Nile mud brought down by the Bahr Yussef, 15 miles (24 km) in length. Between the beginning of Bahr Yussef at El-Lahun to its end at the city of Faiyum, several canals branch off to irrigate the Faiyum Governorate. The drainage water flows into Lake Moeris.

The fertile Nile River Valley stands out against the surrounding sparsely vegetated Sahara Desert in this FAPAR image of Egypt and the Sinai Peninsula. The Fraction of Absorbed Photosynthetically Active Radiation of such images corresponds to the vegetation index of a given zone.

Most of the Nile River Valley and Delta appears green, ranging between 0.4 and 0.8 on the spectrum of photosynthetic activity,  while the surrounding desert areas show values between 0.0 and 0.2, indicating very low activity. Upon opening the full image, the Nile River can be seen continuing south to Lake Nasser, which shows no signs of vegetation around it.

While the desert landscape may appear calm in the thumbnail, upon opening the full image Sahara sands can be seen blowing from southern Libya upwards into northern Libya and Egypt.

Providing a cool color change from the warm desert reds and yellows, the green Nile Valley, in Egypt, is visible in the upper right corner, as is the blue Mediterranean Sea at the top.

Standing out as a fertile green area amidst the yellow, arid desert, the Faiyum Oasis is a distinctive region between the main Nile Valley and other desert oases.

It is a depression in the desert immediately to the west of the Nile south of Cairo whose area is estimated to vary between 490 mi² (1,270 km²) and 656 mi² (1700 km²).

Much of its floor is fields watered by a channel of the Nile, the Bahr Yussef, as it drains into a desert depression to the west of the Nile Valley. The Bahr Yussef veers west through a narrow neck of land north of Ihnasya, then branches out, providing rich agricultural land in the Faiyum basin, and finally drains into the large saltwater Lake Moeris (Birket Qarun).

Lake Moeris was freshwater in prehistory but is today a saltwater lake. The lake’s surface is 140 ft (43 m) below sea-level, and covers about 78 mile² (200 km²). Its area is estimated to vary between 490 mi² (1,270 km²) and 656 mi² (1,700 km²).
