WebDepartment of Geography, Hull University ABSTRACT. Hypotheses developed to explain meandering in river channels often demand excess energy to initiate bank erosion, which is usually assumed to occur in the location of a pool. Field observations of variations of channel geometry in riffle-pool sequences on the River Fowey, Cornwall, England A riffle is a shallow landform in a flowing channel. Colloquially, it is a shallow place in a river where water flows quickly past rocks. However, in geology a riffle has specific characteristics.

WebBraids and Meanders, Riffles and Pools At channel confluences in braided rivers, there is deep scour, and this material is deposited in bars downstream. This is significant to braided river morphology and mechanics. Ashmore et al. (1992) wished to measure downstream and cross-stream flows at channel confluences in braided rivers. Web1 day ago · The riffle is a bed feature with gravel or larger size particles. The water depth is relatively shallow and the slope is steeper than the average slope of the channel.
