NILE RIVER BASIN

ISS002-701-10 From its headwaters in the Ethiopian Plateau to the delta fringe on the Mediterranean, the Nile - longest river in the world -- is some 6,695 km/4,160 mi long. In addition to the upper reaches of the Nile, individual volcanic craters of the Ethiopian Plateau are easily observable in this detailed photo.

ISS002-722-77 Faiyum Depression, Egypt. The depression, which lies north of Cairo and west of the Nile, is intensively farmed as there is water at the surface (Lake Qarun is longer water body) and in the shallow subsurface. All the light gray patches are cities and towns; roads are visible as well.

ISS002-710-14 Nile valley, Egypt. In recent years, agricultural activities have expanded beyond the boundaries of the dark green Nile River delta; ground water is being mined to irrigate fields west of the River. Between Cairo and the pyramids at Giza the edge of the delta is defined by a stream-cut escarpment more than 100 ft high.

ISS002-724-80 Egyptian desert west of Lake Nasser. With the development of the new lakes and settlements west of Lake Nasser, new roads and canals can been seen extending westward into the desert.

ISS002-724-85 Lake Nasser, western arm. Owing to ample rains during the past three years, water levels are high in Lake Nasser, as seen in this telephoto view. Dust is being blown across the western arm.

ISS002-728E-16 Toshka Lakes, west of Nile River, Egypt. These three fine, detailed telephoto views of the expanding Toshka Lakes permit us to monitor the development of this ambitious water-diversion project and to quantify the changes that have occurred during just the past three years (ISS002-728E-15, ISS002-728E-16, ISS002-728E-17).
