Maurya Department of Geology, Fuculr) of Science, MS. University of Baroda, Baroda, 390 002, India Received 20 June 1995; accepted 29 April 1996 Abstract The Narmada alluvial fan is one of the world largest, … Matrix support, a clay content of 3% and clast contact indicate that the clast-support mechanism resulted from a combination of buoyancy and dispersive pressure. The best example of an alluvial fan is the one in Nepal created by the streaming Koshi River. Chamyal *, A.S. Khadkikar, J.N. The Narmada alluvial fan is one of the world's largest, with an axial length of 23 km.
Near the mountains south of the Taklamakan Desert in Xinjiang, China lies an alluvial fan 25 miles long and nearly as wide. The best example of an alluvial fan is the one in Nepal created by the streaming Koshi River.
Alluvial fan definition, a fan-shaped alluvial deposit formed by a stream where its velocity is abruptly decreased, as at the mouth of a ravine or at the foot of a mountain.
Flooding on alluvial fans can be damaging as the fans have steeper gradients than river floodplains. One of the largest and most prominent examples of an alluvial fan is the megafan at the Koshi River in Nepal.

Aided by the wet climate in the region, the fan spreads over an area of around 15,000 square kilometers. It has an area of almost 15000 square kilometers. Here are some images of the simulated formation of a coalescing alluvial fan from two sources over a period of approximately 30,000 years, entailing tens of thousands of individual discharge events (this took under a couple of hours of CPU time on a reasonably fast Windows-based computer): Examples of Alluvial Fan Landforms: Death Valley National Park, California, USA.

Malik, D.M. It has an area of almost 15000 square kilometers. The architecture is dominated by debris-flow deposits (Gms facies). Alluvial fan definition is - the alluvial deposit of a stream where it issues from a gorge upon a plain or of a tributary stream at its junction with the main stream. It is an alluvial plain for the greater part, but contains some sandy tracts, as in Ruble and Arauco; in the north very little natural forest is found except in the valleys and on the slopes of the enclosing mountain ranges, but in the south, where the rainfall is heavier, the plain is well covered with forest. An alluvial fan is a build up of river or stream sediments which form a sloping landform, shaped like an open fan or a segment of a cone. A good example would be the ones in Death Valley, California. Alluvial fan activity near Flaxmill Creek, Makarora East Exiting the Himalayan foothills onto the level plains, the river itself traverses into India and eventually feeds into the Ganges.
