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]
An alluvial fan and a playa fill the bottom of the crater, [2] which is the lowest point in this volcanic field, [4] while its margins are surrounded by tephra beds including ash, lapilli, scoria and tuff blocks; it appears that most of these are older rocks that were torn out of the ground and ejected during the formation of Lunar Crater. [39]
Mojave has alluvial fans that look remarkably similar to landforms in the Mojave Desert in the American southwest. Fans inside and around the outsides of the crater are closely similar to Earth's alluvial fans. As on Earth, the largest rocks are near the mouths of the fans.
Bajada – compound Alluvial fan; Bar – Natural submerged sandbank that rises from a body of water to near the surface; Bayou – Body of water in flat, low-lying areas; Bench – Long, relatively narrow land bounded by distinctly steeper slopes above and below
A subaqueous fan is a fan-shaped deposit formed beneath water (similar to deltas or terrestrial alluvial fans), that is commonly related to glaciers [1] and crater lakes. [ 2 ] Subaqueous fan deposits are generally described as coarse to fine gravel and/or sand , with variable texture and sorting.

Process-debris is transported by small streams or snow avalanches from valley walls and deposited at the break in valley wall slopes. [1] A debris cone consists of debris deposited in a conical shape with a surface slope greater than 10 degrees (perpendicular to contours), usually transported by small streams or snow avalanches. A debris cone ...
