In addition, we investigated the relationship of the modern stream to relict meander scars left in the nearby stream valley. We found that, despite erosion control measures, the stream continues to

2006年8月1日 · Example of reoccupied paleo-meander loops and valley scarp walls interpreted to be paleo-meander scars, San Felipe 7.5 minute quadrangle. Coarse-grained late Pleistocene sediments lie approximately 3–5 m below the Modern surface, and Pleistocene channels are commonly reoccupied.

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...a meandering stream." [2][3][4] They are often formed during the creation of oxbow lakes. [5][6][7]

We used measurements of the radii of the putative relict meander bends and of their paleochannel widths to estimate paleodischarge of the Pliocene Mississippi River based on equations empirically derived from modern meandering rivers.

2019年2月25日 · The valley margin is distinguished on the basis of tonal contrast and relict valley features like oxbow lakes, abundoned channels, meander scars, etc. The active floodplain of the Ganga River in the study area is demarcated by geomorphic features as point bar, chute channel, lateral bar (bank attached bar), flood channel, etc. and tonal contrast.

2014年1月1日 · This floodplain, known as the Deweyville complex, is recognized by fluvial terrace features along many large streams on the Gulf and Atlantic Coastal plains, including the Sabine River, and is characterized by “giant” meander scars three to six times larger than modern channels (Bernard 1950; Gagliano and Thom 1967; Saucier 1994) .

2008年12月1日 · In addition, we investigated the relationship of the modern stream to relict meander scars left in the nearby stream valley. We found that, despite erosion control measures, the stream continues to undercut its banks. Rates of lateral migration are much less than in unaltered sections of stream.

Alluvial terraces characterized by large relict meander scars at levels between the Pleistocene Beaumont terrace and Holocene surfaces along the Sabine River were designated as the Deweyville terrace by Hugh Bernard in 1950.

The large black circles are Beas sites; the dashed line, the ancient Beas and the dark flowing lines, the relict meander scars visible in three locations. One relict meander shows a channel that runs parallel 21 to the Beas and was contemporary with Chak 9012L (see Fig. 1 for the location of Chak 90-12L), a site that was occupied in the Early ...

2023年8月31日 · Meander scars are observed around the Brahmani and Baitarani rivers, and their OSL chronology dates back to early-mid Holocene times (Dash et al., 2020). These meander scars are indicative of channel shift. As the channel shifting occurred due to avulsion, the meander scars developed along the paleo-flow paths.
