Alluvial fans have also been found on Mars and Titan, showing that fluvial processes have occurred on other worlds. Some of the largest alluvial fans are found along the Himalaya mountain front on the Indo-Gangetic plain. A shift of the feeder channel (a nodal avulsion) can lead to catastrophic flooding, as occurred on the Kosi River fan in 2008.
An alluvial fan could have been deposited and formed outside of a mountain range, however, thrusting of the mountain belt could cause the alluvial fan to become broken up by the new mountain forming. Thus, the alluvial fan would be split with the fan on either side of the new mountain range development and could change the steepness of the fan. [1]
A desert pavement, also called reg (in western Sahara), serir (in eastern Sahara), gibber (in Australia), or saï (in central Asia) [1] is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans. [2] Desert varnish collects on the exposed surface ...
The alluvial plain at piedmont is composed of Alluvial fans which can be found in this area, and which are located at the foot of the rocky mountains. [4] The size of this belt depends on the amount of runoff and weathering materials from the rocky mountains. [4] Old alluvial fans are covered with eolian loess. Further from the rocky mountains ...
Distributaries are a result of river bifurcation and are often found where a river approaches a lake or an ocean and divides into distributary networks; as such they are a common feature of river deltas. [1] They can also occur inland, on alluvial fans, or where a tributary stream bifurcates as it nears its confluence with a larger stream. In ...
The alluvial fan of Punata in the Valle Alto, east of Cochabamba, is fed by the Rio Paracaya river with a higher average discharge than the Hableh Rud, and consequently is fairly flat. [3] The alluvial fan of Punata is found in the district of Cochabamba, Bolivia. The region of Punata, at the upper end of the Valle (valley) Alto, at about 2800 ...

The Hilly Flanks share similar characteristics with other foothill chains, including the alluvial fans along the Jordan Valley, the Inner Asian Mountain Corridor, which is a region spanning from the Atlai Mountains in Siberia to the Hindu Kush area of Afghanistan and Pakistan, and the northern China Foothill Arc. The characteristics shared ...
