Meander. A stream bed following a tilted valley. The maximum gradient is along the down-valley axis represented by a hypothetical straight coast channel. Meanders develop, which lengthen the course of the stream, decreasing the gradient. A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse.
In hydrological and fluvial landforms, the thalweg is a line drawn to join the lowest points along the length of a stream bed or valley in its downward slope, defining its deepest channel. The thalweg thus marks the natural direction (the profile) of a watercourse. The term is sometimes used to refer to a subterranean stream that percolates ...
Fish or cut bait is a common English language colloquial expression, dating back to the 19th-century United States, that refers to division of complementary tasks. This expression has multiple uses that have evolved over time, but all generally convey that an important decision must be made, often immediately, and failing to make a choice is to make onesself a useless obstruction.
Cut banks along the Cut Bank Creek. A cut bank, also known as a river cliff or river-cut cliff, is the outside bank of a curve ( meander) in a water channel ( stream ), which is continually undergoing erosion. [1] Cut banks are found in abundance along mature or meandering streams, they are located opposite the slip-off slope on the inside of ...
In fisheries and conservation biology, the catch per unit effort ( CPUE) is an indirect measure of the abundance of a target species. Changes in the catch per unit effort are inferred to signify changes to the target species' true abundance. A decreasing CPUE indicates overexploitation, while an unchanging CPUE indicates sustainable harvesting.
Ocean current. Distinctive white lines trace the flow of surface currents around the world. An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.

An oxbow lake is a U-shaped lake or pool that forms when a wide meander of a river is cut off, creating a free-standing body of water. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream. In South Texas, oxbows left by the Rio Grande are called resacas.
The Sea Cut (Scalby Beck) [note 3] [3] is a small river that enters the North Sea at Scalby Mills, Scarborough, North Yorkshire, England. The beck is fed from local streams in Scalby, Newby and Burniston and other watercourses draining off the nearby hills. It is also a bypass channel for the upper reaches of the River Derwent when it is under ...
