Downstream may refer to: Downstream (hydrology) , the direction towards the mouth of a stream, i.e. the direction the current flows Downstream (bioprocess) , when a cell mass from an upstream process (isolated, grown and harvested) is further processed to meet purity and quality requirements
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 ...
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.
A stone near Crissolo, Italy, inscribed: Here is born the Po. The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to the most distant headwater source (irrespective of stream name), or from the mouth to the headwaters of the stream commonly known as the source stream".
Typically, over time the meanders gradually migrate downstream. If some resistant material slows or stops the downstream movement of a meander, a stream may erode through the neck between two legs of a meander to become temporarily straighter, leaving behind an arc-shaped body of water termed an oxbow lake or bayou. A flood may also cause a ...
Due to the anti-parallel nature of DNA, this means the 3' end of the template strand is upstream of the gene and the 5' end is downstream. Some genes on the same DNA molecule may be transcribed in opposite directions. This means the upstream and downstream areas of the molecule may change depending on which gene is used as the reference.
Common terms to name individual river distributaries in English-speaking countries are arm and channel.These terms may refer to a distributary that does not rejoin the channel from which it has branched (e.g., the North, Middle, and South Arms of the Fraser River, or the West Channel of the Mackenzie River), or to one that does (e.g. Annacis Channel and Annieville Channel of the Fraser River ...
An anabranch is a section of a river or stream that diverts from the main channel or stem of the watercourse and rejoins the main stem downstream. Local anabranches can be the result of small islands in the watercourse. In larger anabranches, the flow can diverge for a distance of several or even hundreds of kilometers before rejoining the main ...
