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 ...
Side valley – Valley with a tributary to a larger river; Sinkhole – Geologically-formed topological depression; Sound – A long, relatively wide body of water, connecting two larger bodies of water; Spit – Coastal bar or beach landform deposited by longshore drift; Spring – A point at which water emenges from an aquifer to the surface
Along a strike valley, smaller tributaries feed into the steep slopes of mountainsides. These tributaries enter the main river about perpendicular, causing a trellis-like appearance of the system. They form where hard and soft formations exist on both banks of the main river, and are reflective of height, accentuated by erosion.
Strike and dip are generally written as 'strike/dip' or 'dip direction,dip', with the degree symbol typically omitted. The general alphabetical dip direction (N, SE, etc) can be added to reduce ambiguity. For a feature with a dip of 45° and a dip direction of 75°, the strike and dip can be written as 345/45 NE, 165/45 NE, or 075,45.
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.
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 ...
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 ...
