Alluvial Fans Formed by Channelized Fluvial
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...
متن کاملSedimentology of the of Zayandeh-Rood River alluvial Terraces and the sediment source identification
In this research, three alluvial Terraces that are located in pathway of Zayandeh-Rood River are studied. The river starts from Bakhtiayri Zardkoh mountain and after through Esfahan city ends to Gawkhony lake. Age of alluvial terraces is younger in upstream than downstream and the height level of the terraces decrease relative to current river bed toward the downstream. The terraces were sample...

15 صفحه اولQuaternary alluvial fans in the Gobi of southern Mongolia: evidence for neotectonics and climate change
Alluvial fans in southern Monglia occur along a group of narrow discontinuous mountain ranges which formed as transpressional uplifts along a series of strike-slip faults. They provide information on the nature of neotectonic activity in the eastern Gobi Altai range and on palaeoclimate change. Alluvial fan formation was dominated by various geomorphological processes largely controlled by clim...
