What is an Interfluve in geography?

: the area between adjacent streams flowing in the same direction.

Where is an Interfluve?

/ˈɪn.t̬ɚ.fluːv/ a higher area between the valleys of streams or rivers: Interfluves are areas of high terrain located between valleys. In the Danube-Tisza interfluve, lakes are threatened by environmental problems. More examples.

How interfluve is formed?

These landforms are created by earth flow (“solifluction”). They can also be former river terraces that are subsequently bisected by fluvial erosion. In cases where there is a deposit of younger sedimentary beds (loess, colluvium) the interfluves have a rounder and less rugged appearance.

What are scalloped interfluves?

The scalloped interfluves, or bars, are the central, higher parts of the doab, with old alluvium of relatively uniform texture. The boundaries of the scalloped features are formed by river-cut scarps at places over 20 feet (6 metres) high.

What are non perennial rivers?

The non-perennial rivers are rivers like Narmada, Tapati, Mahanadi, Godavari, Krishna, Pennar, and Cauvery rivers that have no flow for at least a part of the year.

What is episodic river?

Episodic rivers: Rarely occurring rivers formed from runoff channels in very dry regions. Perennial rivers: Rivers that have a constant stream-flow throughout the year, usually located in more humid climates where rainfall exceeds evaporation rates.

What is the difference between ephemeral and intermittent streams?

Intermittent: streams that hold water during wet portions of the year. Ephemeral: a channel formed by water during or immediately after precipitation events as indicated by an absence of forest litter and exposure of mineral soil.

Is oxbow lake?

Oxbow lake, small lake located in an abandoned meander loop of a river channel. It is generally formed as a river cuts through a meander neck to shorten its course, causes the old channel to be rapidly blocked off, and then migrates away from the lake.

How is drainage density measured?

Drainage density This relates to the number of streams in a particular drainage basin and can be measured by dividing total length of all streams in a basin (L) by its area (A). As a rule, the higher the drainage density (D) the more quickly water drains to a river.

Which river is called perennial?

For e.g.,Ganga is the best example of a perennial river. These rivers get water by rain in rainy season, melting of ice in summer and by snow in the winter season. Other examples include the Indus and its five tributaries, they are Chenab, Jhelum, Beas, Ravi and Sutluj.
