The festival of the Nile as depicted in Norden's Voyage d'Egypte et de Nubie Map of the Nile river. The flooding of the Nile (commonly referred to as the inundation) has been an important natural cycle in Nubia and Egypt since ancient times. It is celebrated by Egyptians as an annual holiday for two weeks starting August 15, known as Wafaa El-Nil.
A nilometer is a structure for measuring the Nile River's clarity and water level during the annual flood season in Egypt. [1] There were three main types of nilometers, calibrated in Egyptian cubits: (1) a vertical column, (2) a corridor stairway of steps leading down to the Nile, and (3) a deep well with a culvert. [1]
Although it dates to the 5th dynasty, the Palermo stone recorded the level of the Nile River during the reign of the Early Dynastic pharaoh Djer, when the height of the Nile was recorded as 6 cubits and 1 palm (about 3.217 m or 10 ft 6.7 in). [2] A Third Dynasty diagram shows how to construct a circular vault using body measures along an arc ...
The Sobat River, which joins the Nile a short distance below Lake No, drains about half as much land, 225,000 km 2 (86,900 sq mi), but contributes 412 cubic meters per second (14,500 cu ft/s) annually to the Nile. [47] When in flood the Sobat carries a large amount of sediment, adding greatly to the White Nile's color. [48]
A road going through the flooded savannah The Nile Delta upstream of Cairo in 1961. At the northern end is the Nile Delta, 175 km long by 260 km wide. There are some lakes and lagoons with marshes near the seacoast; some of the larger are Lake Burullus and Lake Manzala. The topsoil in the delta is up to 21 meters in depth and intensely used for ...
The success of ancient Egyptian civilization came partly from its ability to adapt to the conditions of the Nile River valley for agriculture. The predictable flooding and controlled irrigation of the fertile valley produced surplus crops, which supported a more dense population, and social development and culture.
The dam has a length of about 9 kilometres (5.6 mi) and a crest height of up to 67 metres (220 ft). It consists of concrete-faced rockfill dams on each river bank (the right bank dam is the largest part of the project, 4.3 km long and 53m high; the left bank is 1590 metres long and 50 metres high), an 883-metre (2,897 ft)-long 67-metre (220 ft)-high earth-core rockfill dam (the 'main dam') in ...
The Aswan Low Dam or Old Aswan Dam is a gravity masonry buttress dam on the Nile River in Aswan, Egypt. The dam was built by the British at the former first cataract of the Nile, and is located about 1000 km up-river and 690 km (direct distance) south-southeast of Cairo. When initially constructed between 1899 and 1902, nothing of its scale had ...
