Herodotus, a Greek historian, first used the term "delta" for the Nile River in Egypt. The Nile is formed by three principal streams: the Blue Nile (Arabic: Al-Baḥr Al-Azraq; Amharic: Abay) and the Atbara (Arabic: Nahr ʿAṭbarah), which flow from the highlands of Ethiopia, and the White Nile (Arabic: Al-Baḥr Al-Abyad), the headstreams of which flow into Lakes Victoria and Albert.. In the Nile Delta for example, the Egyptians constructed their towns and cemeteries on turtlebacks; natural highpoints in the landscape that became islands during the inundation. This kind of delta is a lot more solid and mimics the shape of a triangle. Thus, this delta rarely occurs along ocean coasts because the waves are often stronger than the river current. Rivers typically contain their highest sediment loads near their mouth, where they meet seas and oceans. According to wikipedia, the Arabic name of the Nile delta is also delta (or dalta), which may or may not mean that this name is fairly old. It’s a curved or bowed delta with the convex margin facing the sea. Experts warn that global warming will have a major impact in the delta on agriculture resources, tourism and human migration besides shaking the region's fragile ecosystems. Heavy spring floodwaters from throughout central Egypt inundate the river with sediment every year, and over millennia these sediments were deposited along the river banks to create the fertile river valley. This is because the sediment land mass developed at mouth of this river formed a triangular shape that looks like the upper case Greek letter delta. The formation of a river delta is a slow process. From north to south the delta is approximately 160 km in length. Air views of Palestine. The Nile Delta ( Arabic : دلتا النيل Delta n-Nīl or simply الدلتا ed-Delta ) is the delta formed in Northern Egypt (Lower Egypt) where the Nile River spreads out and drains into the Mediterranean Sea. Since the delta no longer receives an annual supply of nutrients and sediments from upstream due to the construction of the Aswan High Dam, the soils of the floodplains have become poorer, and large amounts of fertilizers are now used. When the river’s flow slows down, the size of the particles decreases because larger particles are deposited first. 3 Main Types of Delta. have plants that grow in abundance. The sediment is dropped at the mouth of the river. Two large distributaries built major lobes, wave action in the Mediterranean redistributes sediment at the front of the delta, this sediment forms a series of curved barrier bars which form closed off segments of the Mediterranean sea, these segments are called lagoons The Delta has a hot desert climate as the rest of Egypt, but its northernmost part, as is the case with the rest of the northern coast of Egypt which is the wettest region in the country, has relatively moderate temperatures, with highs usually not surpassing 31 °C (88 °F) in the summer. Deltas form when silt and sediments accumulate at the mouths of large rivers. In the past, the delta had several distributaries, but these have been lost due to flood control, silting and changing relief. These distributaries appear like a maze of water channels. Environmental damage to the Nile Delta is not yet one of Egypt's priorities, but experts say if the situation continues to deteriorate, it will trigger massive food shortages which could turn seven million people into "climate refugees. To the north-west are three other coastal lakes or lagoons: Lake Burullus, Lake Idku and Lake Maryut. The name Nile is derived from the Greek Neilos (Latin: Nilus), which probably originated … On the western riverbank, these necropoli (cities of the dead) were built on a gravelly desert plateau formed of limestone and clay overlooking the river. As the river channel flows over the ground and makes contact with soil, it carries with it sediments like gravel, sand, silt and clay. As the polar ice caps melt, much of the northern delta, including the ancient port city of Alexandria, will disappear under the Mediterranean. Most of Egypt's habitable land is within the Nile Delta and along the Nile River. The Nile Delta. The lagoon is partly enclosed by two long narrow barrier spits that are surmounted by beach ridges and crossed by tidal entrances of variable position and size. It is one of the world's largest river deltas—from Alexandria in the west to Port Said in the east, it covers 240 km of Mediterranean coastline and is a rich agricultural region. The Nile is considered to be an "arcuate" delta (arc-shaped), as it resembles a triangle or lotus flower when seen from above. Information and translations of nile delta in the most comprehensive dictionary definitions resource on the web. Basin modeling in the eastern part of the Nile Delta … The bird’s foot delta got its name because it forms like a bird foot’s claw. A delta can only form when river channels carry sediments into another body of water. It is one of the world's largest river deltas—from Alexandria in the west to Port Said in the east, it covers 240 km of Mediterranean coastline—and is a rich agricultural region.
