alluvial fan
A cone-shaped heap of alluvium deposited by a river
A fan-shaped sediment deposit formed by a stream that flows from a steep mountain valley or gorge onto a plain or the junction of a tributary stream with the main stream Alluvial fans contain active stream channels and boulder bars, and recently abandoned channels Alluvial fans are predominantly formed by alluvial deposits and are modified by infrequent sheetflood, channel avulsions and other stream processes They may also be subject to debris flow and debris torrents
Used to describe the fanning aspect of a stream as it leaves a mountain to disperse in a valley; also used in desert areas to describe the effects of a mineral breaking off the steep sides of mountains and being spread by later effects of water or wind
A triangular deposit of sediment left by a stream that has lost velocity upon entering a broad, relatively flat valley
A low, outspread mass of loose materials and/or rock material, commonly with gentle slopes, shaped like an open fan or a segment of a cone, deposited by a stream (best expressed in semiarid regions) at the place where it issues from a narrow mountain or upland valley; or where a tributary stream is near or at its junction with the main stream It is steepest near its apex which points upstream and slopes gently and convexly outward (downstream) with a gradual decrease in gradient GG
A fan-shaped deposit of unconsolidated material and debris, forming at the point where a stream emerges from a narrow valley onto a broader, less sloping valley floor
A low, outspread, relatively flat to gently sloping mass of loose rock material, shaped like an open fan or a segment of a cone, deposited by a stream (esp in a semiarid region) at the place where it issues from a valley upon a plain or broad valley, or where a tributary stream is near or at its junction with the main stream, or wherever a constriction in a valley abruptly ceases or the gradient of the stream suddenly decreases; it is steepest near the mouth of the valley where its apex points upstream, and it slopes gently and convexly outward with gradually decreasing gradient
A fan-shaped accumulation of alluvium deposited at the mouth of a ravine or at the juncture of a tributary stream with the main stream
A dry-land counterpart of deltas
A low, outspread, relatively flat to gently sloping mass of loose rock material deposited by a stream where it flows from a narrow mountain valley onto a plain or broad valley
A cone-shaped deposit of alluvium made by a stream where it runs out onto a level plain or meets a slower stream
A low cone-shaped deposit of material laid down by a swift-flowing stream as it enters a plain or an open valley
a cone of sediment deposited at an abrupt change of slope
a fan-shaped deposit where a fast flowing stream flattens out
A large, fan-shaped pile of sediment forming at the base of narrow canyons onto a flat plain at the foot of a mountain range
A sloping fan-shaped accumulation of sediment found where a stream leaves a narrow valley and spreads out over a broad geographic area Most frequently found in arid areas
a fan-shaped deposit of gravel, sand and silt dropped by a stream where there is a decrease in slope e g from mountains onto a level plain or into a lake or stream
The fan-shaped area built up by alluvial deposits, usually at the foot of a steep slope as it opens onto a valley floor or plain
a fan-shaped body of deposited material typically built where a stream leaves a steep mountain valley
Usually seen at a junction where a small stream joins a larger one or at the point where water flows through a narrow gorge that opens onto a plain, this fan-shaped deposit of soil is left behind
