A wide variety of river and stream channel types exist in limnology, the study of inland waters.All these can be divided into two groups by using the water-flow gradient as either low gradient channels for streams or rivers with less than two percent (2%) flow gradient, or high gradient channels for those with greater than a 2% gradient.
Gravel bar in the American River, Washington, United States. A bar in a river is an elevated region of sediment (such as sand or gravel) that has been deposited by the flow. Types of bars include mid-channel bars (also called braid bars and common in braided rivers), point bars (common in meandering rivers), and mouth bars (common in river ...
Bar Initiation: The braid bar will form following a series of dune amalgamations. As sediments are deposited to form the braid bar, flow in the channel begins to diverge, with the braid bar acting as a wedge. This stage is associated with high flow in the braided river. Bar Growth: Dune amalgamation continues as an accretionary dune front is ...
In geology, strike and dip is a measurement convention used to describe the plane orientation or attitude of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle) measured downward from horizontal. [1]
The Transverse Valleys (Spanish: Valles transversales) are a group of transverse valleys in the semi-arid northern Chile. They run from east to west (traversing Chile), being among the most prominent geographical features in the regions they cross. [1] They are located in the Chilean regions of Valparaíso, Coquimbo, and Atacama.
The valley has an average elevation of 2000 ft. Kangra Valley is a strike valley and extends from the foot of the Dhauladhar range to the south of river Beas. The highest peak on the Dhauladhar, White Mountain, marks the boundary between the valley and Chamba, and reaches 15,956 ft (4,863 m). The peaks of the range are approximately 13,000 ft ...
Stainless steel soap is a piece of stainless steel, in the form of a soap bar or other hand-held shape. Its purported purpose is to neutralize or reduce strong odors such as those from handling garlic , onion , durian , guava , salami , or fish .
Near the glacier the outwash plain is composed of long bars of coarse gravel with very variable grain size, with a few large channels between the bars. Further away there are transverse bars and a web of many braided channels. The sediment now includes gravel and sand, and the grains are rounder due to sorting and abrasion.
