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 ...
Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes. [1]
Ria – Coastal inlet formed by the partial submergence of an unglaciated river valley; River delta – Silt deposition landform at the mouth of a river; Salt marsh – Coastal ecosystem between land and open saltwater that is regularly flooded; Sea cave – Cave formed by the wave action of the sea and located along present or former coastlines
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 ...
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.

A sandy depression formed when wind erodes into patches of bare sand on otherwise vegetation-stabilized sand dunes at the margins of coastal and arid ecosystems. bluff A steep slope or cliff marking the outer margin of a floodplain, especially one formed as the river erodes the concave bend of a meander. See also cut bank. bocage
A point bar is an area of deposition typically found in meandering rivers. Point bars form on the inside of meander bends in meandering rivers. As the flow moves around the inside of the bend in the river, the water slows down because of the shallow flow and low shear stresses there reduce the amount of material that can be carried there.
River rejuvenation can lead to a number of changes in landscape. These include the formation of waterfalls and rapids, knick points, river terraces and incised meanders. [1] Rejuvenated terrains usually have complex landscapes because remnants of older landforms are locally preserved.
