Nile Delta flooded savanna

Nile Delta flooded savanna is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Nile Delta flooded savanna rather than just read about it. In short: The Nile Delta flooded savanna, ecoregion (WWF ID: PA0904) covers both the Nile Delta proper, where the Nile River enters the Mediterranean Sea, as well as the river floodplains of the Nile 1,100 kilometres (680 mi) up-river to the Aswan Dam. Since the Aswan Dam was completed in the 1970s, the Nile on this stretch has not been subject to annual flooding, leading the loss of much of the papyrus sedge (Cyperus papyrus…

Key takeaways

Nile Delta flooded savanna belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Nile Delta flooded savanna to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nile Delta flooded savanna from memory before moving on to harder problems.

Reference excerpt

The Nile Delta flooded savanna, ecoregion (WWF ID: PA0904) covers both the Nile Delta proper, where the Nile River enters the Mediterranean Sea, as well as the river floodplains of the Nile 1,100 kilometres (680 mi) up-river to the Aswan Dam. Since the Aswan Dam was completed in the 1970s, the Nile on this stretch has not been subject to annual flooding, leading the loss of much of the papyrus sedge (Cyperus papyrus) swamps and other marshes along the river.

Location and description

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 agriculture. The soil quality has been degrading, however, due to the loss of additional sediments from floods, and the use of fertilizers has increased. The western coast of the delta is divided from the sea by a portion of the Mediterranean dry woodlands and steppe ecoregion. The ecoregion follows the Nile upriver over 700 km from the delta at Cairo to Aswan, averaging under 20 km wide for that length. For most of the stretch above the delta, the ecoregion is bounded on the east by the North Saharan xeric steppe and woodland ecoregion. Above the halfway point, the ecoregion on the west is the Sahara desert ecoregion.

Climate The climate of most of the river in the ecoregion is hot desert climate (Köppen climate classification (BWh)). This climate features stable air and high pressure aloft, producing a hot, arid desert. Hot-month temperatures typically average 29–35 °C (84–95 °F). Temperatures in the Delta are more Mediterranean. Precipitation averages 100-200 mm/year in the delta, with precipitation levels declining farther south.

Flora and fauna

In the delta, the once characteristic papyrus sedge has been replaced by agricultural cultivation. Outside of the agricultural area, typical delta species are the common reed (Phragmites australis), aquatic bulrushes (Typha capensis), and sea rushes (Juncus maritimus). The coastal marshes feature drought and salt-tolerant shrubs such as Halocnemum and Nitraria retusa. Along the river upstream, the banks support dense growths of reeds (genus Phragmites) and bulrushes (genus Typha). The Nile in Egypt has 533 species of plants, eight of which are endemic. The delta and riverine wetlands of the ecoregion are an important stopping point for migratory birds on the Asian–East African Flyway. Species include the white stork (Ciconia ciconia), black stork (Ciconia nigra), European crane (Grus grus) and the great white pelican (Pelecanus onocrotalus). Many birds winter in the delta, including the little gull (Larus minutus) and the whiskered tern (Chlidonias hybrida). Other waterbirds include the shoveler (Anas clypeata), the Eurasian teal (Anas crecca), the Eurasian wigeon (Anas penelope), the garganey (Anas querquedula), the Kentish plover (Charadrius alexandrinus), and the cormorant (Phalacrocorax carbo).

Protected areas Less than 1% of the ecoregion is officially protected. These protected areas include:

Wadi El Assuti

Worked examples

Example 1 — a first encounter with Nile Delta flooded savanna

Start with the simplest possible case. Write down what Nile Delta flooded savanna claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Nile Delta flooded savanna before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Nile Delta flooded savanna ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Nile Delta flooded savanna

In research: Nile Delta flooded savanna appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Nile Delta flooded savanna in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Nile Delta flooded savanna is common in secondary-school and first-year university syllabi. It links to neighbouring topics Ecoregions of Egypt, Flooded grasslands and savannas, Palearctic ecoregions, so understanding it makes those chapters shorter.
In everyday life: Look for Nile Delta flooded savanna outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
