Incised meanders at “The Goosenecks” on the San Juan River in southern Utah. Cut in resistant limestones to a depth of 260 meters, one of the meanders here measures 14 km in a loop that brings it back to 1 km from itself.

The meanders of a stream or river that has cut its bed down into the bedrock are known as either incised, intrenched, entrenched, inclosed or ingrown meanders. Some Earth scientists recognize and use a finer subdivision of incised meanders.

The meaning of INCISED MEANDER is the curve of a winding river with steep slopes on both sides rising to a former floodplain and usually interpreted as due to rejuvenation of a meandering stream but probably also formed by a combination of vertical and lateral erosion in a single cycle of valley development.

incised channels will tend to widen (due to lateral erosion of their banks), flatten, become more sinuous, and develop a meander pattern along with floodplain characteristics similar to the pre-disturbance condition. In other words, disturbed channels tend to evolve toward a state of dynamic stability appropriate to

Several studies have cited incised meander a major feature of river entrenchment, as an impact of river rejuvenation. On the other hand, scholars argue that incised meanders and entrenched meanders are features formed before river rejuvenation.

When a meander cuts into bedrock it is generally called an incised meander.6 There are two types of incised meanders: 1) an ingrown meander which continues to grow horizontally and vertically, with an asymmetric slope in its walls (Figure 61.1);7 and 2) an entrenched meander with symmetrical, near-vertical walls which cuts downward with little i...

A synonymous term for this phenomenon is incised meanders. Entrenched meanders are commonly ascribed to epeirogeny, although a drop in sea level, or some other process, might have been responsible in some cases. The San Juan River, where it flows through the goosenecks, is not a true meandering stream today, but rather a crooked stream which ...

Incised meanders are meanders which are particularly well developed and occur when a river’s base level has fallen giving the river a large amount of vertical erosion power, allowing it to downcut. There are two types of incised meanders, entrenched meanders, and …

2008年1月1日 · Based on the images of Google Earth, meanders’ parameters are proposed and then measured and calculated. The result suggests that incised meanders in the Jialing River are among the most...

2022年5月21日 · The marginal eastern parts of the Bohemian Massif in Austria are characterized by incised valley meanders, which have formed in response to tectonic uplift and river channel incision starting before c. 5 Ma. The most impressive examples of incised valley meanders are located in the Waldviertel Highlands along the Thaya, Kamp and Krems rivers.
