Along the south margin of the San Gabriel (California) mountain block alluvial fans have accumulated to a thickness of a thousand feet and more. The whole series of sediments is a unit, still growing, but chiefly of Pleistocene or earlier age. The fans are being dissected, with the formation of fanhead trenches and midfan mesas. The trenching of the fanheads is chiefly a normal, somewhat late feature of the fan development, though recent uplift, indicated by well-preserved fault scarps, has… Expand
Processes and Forms of Alluvial Fans
Alluvial fans are a conspicuous conical landform commonly developed where a channel emerges from a mountainous catchment to an adjoining valley (Figs. 14.1 and 14.2). Although present in perhaps allExpand
Alluvial Fan Processes and Forms
Alluvial fans are a prominent landform type commonly present where a channel emerges from mountainous uplands to an adjoining valley. Although occurring in perhaps all global climatic regimes, fansExpand
Principles of Alluvial Fan Morphology
The alluvial fan is a sediment storage in form of a prism by the mountain front, above a local base-level. Fans show in plan-view a triangular cone-shaped form, bridging in between highly erosiveExpand
Characteristics and Origin of a Precambrian Pediment
The unconformity beneath the Torridonian (late Precambrian) sediments of northwest Scotland represents one of the most ancient of fossil landform assemblages. Cut across crystalline Lewisian rocks,Expand
A note on the formation of alluvial fans
Abstract In the area along the northern flank of the Mount Hutt Range, Canterbury, deposition of alluvial fans is initiated in three ways: the sudden release of large quantities of sediment from ntheExpand
Alluvial fans along the foothills of the Elburz Mountains, Iran
Abstract Alluvial fans are particularly well developed along the southern margins of the Elburz Mountains, Iran. In this work, 26 alluvial fans situated to the southeast of Tehran are examined. TheExpand
Processes of Sediment Supply to Alluvial Fans and Debris Cones
Debris cones and alluvial fans involve a range of landform sizes from individual debris-flow lobes, through debris cones and “classic” alluvial fans, to enormous fluvial “megafans” (Harvey 2011).Expand
Neotectonics and stream piracy on the Lyle Creek alluvial fan, Southern California
This paper will examine the geomorphic evolution and demise of the Lytle Creek fan through analysis of the alluvial deposits and the landforms with which they are associated. Stratigraphy andExpand
Development of the Astoria Canyon-Fan physiography and comparison with similar systems
A detailed bathymetric study of Astoria Canyon and Astoria Fan provides a model for typical submarine canyon-fan systems. The present canyon head is 9 miles (17 km) west of the Columbia River mouthExpand
