1. A narrow stretch of floodplain added to the outer end and downstream side of spurs between enclosed meanders on a river. [4] 2. A type of point bar consisting of a low, narrow ridge running in line with the curve of a meander, formed when the river overflows its banks. [4] sea 1. Any large body of salt water surrounded in whole or in part by ...
geosphere - the solid part of planet Earth, the main divisions being the crust, mantle, and liquid core. The lithosphere is the part of the geosphere that consists of the crust and upper mantle. geothermal energy - energy derived from the natural heat of the earth contained in hot rocks, hot water, hot brine or steam. global acres see global ...
The water in this stream forms varying currents as it makes its way downhill. In hydrology, a current in a water body is the flow of water in any one particular direction. The current varies spatially as well as temporally, dependent upon the flow volume of water, stream gradient, and channel geometry.
Conversely, explorers approaching a new land from the sea encounter its rivers at their mouths, where they name them on their charts, then, following a river upstream, encounter each tributary as a forking of the stream to the right and to the left, which then appear on their charts as such; or the streams are seen to diverge by the cardinal ...
This causes erosion on the upstream side of the obstruction and deposition on the downstream side. The deposition that occurs on the downstream side can create a central bar, and an arcuate bar can be formed as flow diverges upstream of the obstruction. [1] Continuous deposition downstream can build up the central bar to form an island ...
As a result, antidunes migrate in an upstream direction, counter to the current flow. Antidunes are called in-phase bedforms, meaning that the water surface elevation mimics the bed elevation; this is due to the supercritical flow regime. Antidune bedforms evolve rapidly, growing in amplitude as they migrate upstream.

The Swedish side of Torne River has a distributary called the Tärendö River, which on average transports 57% of the water of the Torne River into the Kalix River. [20] The Barak River splits into two major rivers at the India-Bangladesh border. [21] The Karnali River bifurcates in Nepal and the two parts rejoin after flowing into India for 80 ...
