Mar 2, 2021 · The straight areas are riffles, curved areas are pools and the spots after these curves are the runs. This is a natural process, where riffles, pools, and runs are formed. Together, the Riffle-Pool-Run sequence re-shapes the landscape around it, creating meandering lines and curving paths of water to flow. These different habitats allow a great ...

Riffle on the Onega River. A riffle is a shallow landform in a flowing channel. [ 1 ] Colloquially, it is a shallow place in a river where water flows quickly past rocks. [ 2 ] However, in geology a riffle has specific characteristics.

pool and riffle, deep and shallow portions of an undulating stream bed. Pools are most easily seen in a meandering stream where the outer edge of each meander loop is deep and undercut; riffles form in the shallow water of the short, straight, wide reaches between adjacent loops. The pools and riffles form sequences spaced at a repeating ...

Riffle: A high-gradient bar of deposited substrate, usually spanning the width of a stream. Typically found as part of a riffle-pool repeating sequence in streams of medium gradient.
Mar 13, 2021 · A-level biology glossary. This glossary contains many of the terms in A-level biology, in addition to many terms which are well beyond the A-level syllabus. You really don’t need to know all of these words, but including some words which aren’t in A-level biology in your essays can help you get higher marks.

Dec 13, 2017 · A riffle is a shallow landform (elevated river bed) on a stream where water runs fast and in an agitated manner due to sediment deposits below the place. Mostly, riffles form in the shallow straight waters between loops. In most cases, a pool forms immediately after a riffle thus forming a sequence of riffle-pool features on a given length of a ...
