Alluvial Fan

Alluvial fan soils are transported by water down steep mountain slopes during periods of intense rainfall and are deposited close to their mountainous source. The distributiuon of soil types is a function of the gradient and distance from the source as shown in the cross section (Sowers, 1978).
