The term “Fan” was first time coined by Haast in his work about Canterbury Plains on 1864. He consider that these plains were fan shaped developed by the depositional work from the Pleistocene Glaciers. After a century (1964) Carryer put out the concept that the Alluvial fans are formed in the foothill zone produced by the depositional work by river or water. “Alluvial fans and Cones due accumulation of materials are always famed at the base of foothills where there is abrupt drop (decrease) in the channel gradient.” (Savindar Singh). “An alluvial fan is a body of sediment whose surface form approximates to the segments of a cone which radiates down slope from a point on a mountain front, usally where a stream emerges.” (Michael A Summerfie
