A delta forms where a river meets a lake. [10] River deltas form when a river carrying sediment reaches a body of water, such as a lake, ocean, or a reservoir. When the flow enters the standing water, it is no longer confined to its channel and expands in width. This flow expansion results in a decrease in the flow velocity, which diminishes ...
The Nile Delta (Arabic: دلتا النيل, Delta an-Nīl or simply الدلتا, ad-Delta) is the delta formed in Lower Egypt where the Nile River spreads out and drains into the Mediterranean Sea. [1] It is one of the world's larger deltas—from Alexandria in the west to Port Said in the east; it covers 240 km (150 mi) of the Mediterranean ...
300 yrs BP, 500 yrs BP, current. A deltaic lobe is a wetland formation that forms as a river empties water and sediment into other bodies of water. As the sediment builds up from this delta, the river will break away from its single channel and the mouth will be pushed outwards, forming a deltaic lobe. [1]
The Yellow River[ a ] is the second-longest river in China and the sixth-longest river system on Earth, with an estimated length of 5,464 km (3,395 mi) and a watershed of 795,000 km 2 (307,000 sq mi). Beginning in the Bayan Har Mountains, the river flows generally eastwards before entering the 1,500 km (930 mi) long Ordos Loop, which runs ...
A bar in a river is an elevated region of sediment (such as sand or gravel) that has been deposited by the flow. Types of bars include mid-channel bars (also called braid bars and common in braided rivers), point bars (common in meandering rivers), and mouth bars (common in river deltas). The locations of bars are determined by the geometry of ...
a U-shaped lake formed when a wide meander from the mainstem of a river is cut off to create a lake. Phytotelma: a small, discrete body of water held by some plants. Plunge pool: a depression at the base of a waterfall. Pool: various small bodies of water such as a swimming pool, reflecting pool, pond, or puddle. Pond
A kame delta (or ice-contact delta, morainic delta[1]) is a glacial landform formed by a stream of melt water flowing through or around a glacier and depositing material, known as kame (stratified sequence of sediments) deposits. Upon entering a proglacial lake at the end (terminus) of a glacier, the river/stream deposit these sediments.
Nile. The Nile[b] (also known as the Nile River) is a major north-flowing river in northeastern Africa. It flows into the Mediterranean Sea. The Nile is the longest river in Africa.
