A river delta is a landform created by deposition of sediment that is carried by a river as the flow leaves its mouth and enters slower-moving or stagnant water. [1] [2] This occurs where a river enters an ocean , sea , estuary , lake , reservoir , or (more rarely) another river that cannot carry away the supplied sediment.

overall geometry of the alluvial fan. Sheetflood facies associations are distinctive in the alluvial fan system and consist of basal planar-bedded couplets overlain by normally graded beds of boulders, pebbles and cobbles, which can exhibit clast imbrication and crude cross-bedding, and fine with spatial migration from the source. overall geometry of the alluvial fan. Sheetflood facies associations are distinctive in the alluvial fan system and consist of basal planar-bedded couplets overlain by normally graded beds of boulders, pebbles and cobbles, which can exhibit clast imbrication and crude cross-bedding, and fine with spatial migration from the source. Alluvial fans (Fig. 1) are prominent depositional landforms found in all global climatic regimes (Fig. 2) and serve as a transitional environment between a degrading upland area and adjacent lowland (Harvey, 1997). Alluvial fans are built unevenly; varying amounts and size of debris, volume of water, and placement of previous deposits influence where the alluvium is left. Usually, the larger rocks are closest to the topographic break, while finer grains travel further before being deposited. Some areas of the fan build up more sediment than others over years.

Apr 03, 2015 · Both are structures that form as a moving body of water deposits most of the sediment load that it's carrying. The major difference is where that load gets deposited and what type of sediments comprise it.

Alluvial Fan. A fan-shaped wedge of sediment that typically accumulates on land where a stream emerges from a steep canyon onto a flat area. In map view it has the shape of an open fan.

It shows an uplifted fan surface that has been subsequently trenched, which is acting to focus the incised channel a younger alluvial fan that is prograding out into the valley floor. The juxtaposition of active and inactive fans is a common feature, both in space and in time, which can make the stratigraphy of these things sort of complicated. CHAPTER 4 ALTERNATE BARS AND ALLUVIAL FANS 4.1 INTRODUCTION At least as interesting as the mechanism of sediment transport itself is the ability of rivers to construct morphologies. Primary among these morphologies is the river itself, with a definable self-formed channel maintaining consistent bankfull geometry, as well as a floodplain.

Feb 28, 2018 · In Earth science, by definition, an alluvial fan is a fan-shaped deposit that gets formed when a stream of water flowing rapidly down a steep gradient enters an area having a gentle slope, slows down, flattens, and spreads out depositing gravel, sand, and smaller pieces of sediment, such as silt―together known as alluvium―in that area.
