Morphogenesis and Morph anthropic Agent Analyses on Creation and evolution of Alluvial fans (Case study: Katoeh, Rigabad and Chenar Alluvial fans- Darab Faultic Valley)
author
Abstract:
Darab Plain is among region that in there formed several alluvial fans because presence of situation and climate change, and can mention to Katoeh, Rigabad and Chenar alluvial fans. In this research is tried to using of Geology and Topographic Maps, Arial Image ana Field survey analysis are discussed Factors affecting the establishment and evolution of this alluvial fans. Result showed that Katoe and Chenar Rivers have high pure force because sharp steep of bed and increase of velocity, and is Prevailing practice of digging the river bed because excess of force that was transfers the downstream materials from erosion. This agent was caused formation of case study alluvial fans. Alluvial fans morphology of Katoe and Chenar has the unique feature. because deposition act don’t in an open space by Katoe and Chenar rivers, but was limited the left side of katoe alluvial fan by Noro mountain and right side of Chenar alluvial fan with Barfdan Mountain. Also human disarranged natural order of case study alluvial fans evolution with creation of artificial embankments, and sand removal

Large alluvial fans on Mars
[1] Several dozen distinct alluvial fans, 10 to 40 km long downslope, have been observed in highlands craters. Within a search region between 0 and 30 S, alluvial fan-containing craters were found only between 18 and 29 S, and they all occur at around ±1 km of the MOLA-defined Martian datum. Within the study area they are not randomly distributed but instead form three distinct clusters. Fans t...
full textFlooding and Flow Path Selection on Alluvial Fans and Deltas
The surfaces of alluvial fans and river deltas (collectively fans) are often dissected by a small number of channels radiating from the fan apex. On long timescales, channels migrate via avulsion, the process of channel bed deposition and abandonment that often results in catastrophic flooding and loss of life on densely populated fans. We present results of an experimental fan that creates rea...

Alluvial fans and fan-deltas are of three basic types: those built up primarily by the action of constantly avulsing river and stream channels, those constructed by sheet flows, and those resulting from. ~e successive deposition of debris flows. The present analysis is directed toward the first two types. A mechamstic formulation of flow and sediment transport through river channels is combined...

When they reach a flat plain, rivers often deposit their sediment load into a cone-shaped structure called alluvial fan. We present a simplified experimental setup that reproduces, in one dimension, basic features of alluvial fans. A mixture of water and glycerol transports and deposits glass beads between two transparent panels separated by a narrow gap. As the beads, which mimic natural sedim...

full textRelief Threshold for Eolian Sand Transport on Alluvial Fans
Many arid alluvial-fan terraces downwind from eolian sand sources exhibit an abrupt increase in Av-horizon thickness and sand content below a critical elevation which varies from fan to fan. Above this elevation, sand accumulates locally and is not transported across the fan. Below this elevation both coarse and fine eolian sand from nearby playa and channel sources is readily transported acros...
