Alluvial fans: geomorphology, sedimentology, dynamics - introduction. A review of alluvial-fan research
This volume presents a series of papers on the geomorphology, sedimentology and dynamics of alluvial fans, selected from those presented at the 'Alluvial Fans' Conference held in Sorbas, SE Spain in June 2003. The conference was sponsored primarily by the British Geomorphological Research Group and the British Sedimentological Research Group, both organizations affiliated to the Geological Soci...
متن کاملDetermination of Tectonic Activity Based on the Morphology of Alluvial Fan Systems (Case Study: the Northern Slopes of Sabalan Volcanic Mount)
Aims & Backgrounds: Alluvial fans are one of the most prominent phenomena in fluvial geomorphology, which are found mostly on the mountain front. These landforms are affected by climate change and tectonic activity and record their effects. Therefore, we can use them to understand climate change and tectonic activities. The aim of this study was to determine the tectonic activity in the northe...
متن کاملresponse of alluvial fan systems to quaternary climate changes (case study: persian alluvial fan system in northern slope of keyamaki mount in northwest of iran)
â â â parsian alluvial fan system is a part of asyab-kharabeh fluvial system that response it to quaternary climate changes is the main goal of this study. for this aim, climatic proxies and traces in alluvial fan structure were investigated base d o n four categories: aggradation and degradation phases, debris flows, size changes in deposited materials and formation of alluvial fan tufas. pri...
متن کاملControls on alluvial fan long - profi les
Water and debris fl ows exiting confi ned valleys have a tendency to deposit sediment on steep fans. On alluvial fans where water transport of gravel predominates, channel slopes tend to decrease downfan from ~0.10–0.04 to ~0.01 across wide ranges of climate and tectonism. Some have argued that this pattern refl ects grain-size fi ning downfan such that higher threshold slopes are required just...
متن کاملThe Role of Climatic Change in Alluvial Fan Development
Alluvial fans develop at the base of drainages where feeder channels release their solid load (Blair and McPherson, 2009; Leeder et al., 1998; Harvey et al., 2005). A classic fan-shape forms where there is a well-defined topographic apex. Multiple feeder channels, however, often blur the fan-shape resulting in a merged bajada. Alluvial fans can be found in almost all terrestrial settings. These...
