Respuesta :
The Nile River of Africa is the longest river in the world, covering a distance of more than 4,000 miles. Beginning near the equator, the river flows northward through northeastern Africa and passes through Egypt before emptying into the Mediterranean Sea. The Nile River was extremely important to ancient Egypt. Without the Nile, Egypt would be nothing but desert, because the region receives very little rainfall. The Nile has provided Egypt with fertile land since ancient times, allowing one of the greatest civilizations of the ancient world to develop.
Answer:
The Nile Delta is a river delta in Egypt. The Nile's Flooded Savanna ecoregion stretches 1,100 kilometers downstream from the Aswan High Dam to the Nile's mouth when it reaches the Mediterranean Sea.
Explanation:
The delta is approximately 175 kilometers long and 260 kilometers wide (Hughes and Hughes 1992). The riverine floodplains and delta are no longer exposed to annual flooding, and the Cyprus papyrus wetlands that once existed in the wettest parts have all but vanished since the Aswan High Dam was built.
Along the delta's seaward face, the surviving marshland is linked to lakes and lagoons. The delta's outer margins are eroding, and salinity levels in certain coastal lagoons are growing as their proximity to the sea grows.
The Nile is the world's longest river, stretching 6,695 kilometers from the eastern shores of Lake Tanganyika to the Mediterranean Sea, with a basin size of 3,026,000 km2. The Bahr el Jebel, Bahr el Ghazal, and Sebat River, which join to form the White Nile, as well as the Blue Nile and the Atbara River, are the Nile's principal tributaries.
The Nile is only covered by this ecoregion downstream of the Aswan High Dam, when peak floods in September result in a discharge rate of 8,100 m3/sec. The Ethiopian Highlands provide 84 percent of the water to Aswan, while Equatorial East Africa provides 16 percent. As the river flows downstream behind the high dam, it picks up a slew of ephemeral tributaries from the western hills that separate the Nile from the Gulf of Suez. The majority of the year, these seasonal rivers are dry, but during strong winter rainstorms in the highlands, torrents run down the water-worn valleys (Hughes and Hughes 1992).
