A floodplain or flood plain or bottomlands [1] is an area of land adjacent to a river. Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high discharge . [ 2 ]
A series of terraces along a river. The oldest terraces (T1) are higher standing than the younger terraces (T3). The present floodplain (T4) will soon become the youngest terrace surface as the river incises. Terraces can be formed in many ways and in several geologic and environmental settings. By studying the size, shape, and age of terraces ...
The terms river morphology and its synonym stream morphology are used to describe the shapes of river channels and how they change in shape and direction over time. The morphology of a river channel is a function of a number of processes and environmental conditions, including the composition and erodibility of the bed and banks (e.g., sand, clay, bedrock); erosion comes from the power and ...
Based on its geomorphology, saucer-shaped islands called flood-basins characterize anastomosing rivers. [5] These channels are classified as a composite form of which the individual channel belts may have braided, meandering or straight channels .
Yazoo stream [1]. A Yazoo stream (also called a Yazoo tributary [2]) is a geologic and hydrologic term for any tributary stream that runs parallel to, and within the floodplain of a larger river for considerable distance, before eventually joining it.
An overbank is an alluvial geological deposit consisting of sediment that has been deposited on the floodplain of a river or stream by flood waters that have broken through or overtopped the banks. The sediment is carried in suspension , and because it is carried outside of the main channel , away from faster flow, the sediment is typically ...
Other than some notable exceptions in antiquity, geomorphology is a relatively young science, growing along with interest in other aspects of the earth sciences in the mid-19th century. This section provides a very brief outline of some of the major figures and events in its development.
The result is called the Sundborg diagram, or the Hjulström-Sundborg Diagram, in the academic literature. This curve dates back to early 20th century research on river geomorphology and has no more than a historical value nowadays, although its simplicity is still attractive.
