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.
In antidunes, sediment is deposited on the upstream (stoss) side and eroded from the downstream (lee) side, opposite lower flow regime bedforms. As a result, antidunes migrate in an upstream direction, counter to the current flow.

This means the upstream and downstream areas of the molecule may change depending on which gene is used as the reference. The terms upstream and downstream are sometimes also applied to a polypeptide sequence, where upstream refers to a region N-terminal and downstream to residues C-terminal of a reference point.
Upstream, a 1927 film by John Ford; Upstream (networking), direction in which data can be transferred from the client to the server (uploading) Upstream, a newspaper covering the oil and gas industry; Upstream (petroleum industry), sector of the oil and gas industry concerned with searching, exploratory drilling, and well operation
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
Upstream and downstream can refer to: Molecular biology. Upstream and downstream (DNA), determining relative positions on DNA; Upstream and downstream (transduction) ...
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 ...
