  2. Meander - Wikipedia

    en.wikipedia.org/wiki/Meander

    A meander cutoff, also known as either a cutoff meander or abandoned meander, is a meander that has been abandoned by its stream after the formation of a neck cutoff. A lake that occupies a cutoff meander is known as an oxbow lake. Cutoff meanders that have cut downward into the underlying bedrock are known in general as incised cutoff meanders ...

  3. Slip-off slope - Wikipedia

    en.wikipedia.org/wiki/Slip-off_slope

    [3] [6] A terrace on the slip-off slope of a meander spur, known as slip-off slope terrace, can be formed by a brief halt during the irregular incision by an actively meandering river. [7] Aerial photograph of a meander on the Economy River, Nova Scotia. The gravel area on the inside of the meander near the centre-right of the image is a slip ...

  4. Meander cutoff - Wikipedia

    en.wikipedia.org/wiki/Meander_cutoff

    Meander cutoffs directly reduce and tend to indirectly reduce a river’s sinuosity, thus straightening out a river’s channel. [5] Understanding the processes that form meander cutoffs can allow one to predict how a river will evolve in the future which is important for agricultural businesses and controlling future floods. [5]

  5. Meander scar - Wikipedia

    en.wikipedia.org/wiki/Meander_scar

    Meander scars, oxbow lakes and abandoned meanders in the broad flood plain of the Rio Negro, Argentina. 2010 astronaut photo from ISS. A meander scar, occasionally meander scarp, [1] is a geological feature formed by the remnants of a meandering water channel. They are characterized by "a crescentic cut in a bluff or valley wall, produced by ...

  6. Helicoidal flow - Wikipedia

    en.wikipedia.org/wiki/Helicoidal_flow

    Helicoidal flow is the cork-screw-like flow of water in a meander. It is one example of a secondary flow. Helicoidal flow is a contributing factor to the formation of slip-off slopes and river cliffs in a meandering section of the river.

  7. Oxbow lake - Wikipedia

    en.wikipedia.org/wiki/Oxbow_lake

    This picture of the Nowitna River in Alaska shows two oxbow lakes – a short one at the bottom of the picture and a longer, more curved one at the middle-right. The picture also shows that a third oxbow lake is probably in the making: the isthmus or bank in the centre of the most prominent meander is very narrow – much narrower than the width of the river; eventually, the two sections of ...

  8. Entrenched river - Wikipedia

    en.wikipedia.org/wiki/Entrenched_river

    Meanders form where gradient is very gentle, for example in floodplain and delta. Meandering is the feature of the middle and final course of the river. But very deep and wide meanders can also be found cutting hard rocks. Such meanders are called incised or entrenched meanders. The exception is that entrenched meanders are formed during the ...

  9. Patterns in nature - Wikipedia

    en.wikipedia.org/wiki/Patterns_in_nature

    Meanders are sinuous bends in rivers or other channels, which form as a fluid, most often water, flows around bends. As soon as the path is slightly curved, the size and curvature of each loop increases as helical flow drags material like sand and gravel across the river to the inside of the bend.
