Web1 day ago · The water depth is relatively shallow and the slope is steeper than the average slope of the channel. At low flows, water moves faster over riffles, which provides oxygen to the stream. Riffles are found entering and exiting meanders and control the streambed elevation. Pools are located on the outside bends of meanders between riffles. WebJan 27, 2004 · However, as you have access to this content, a full PDF is available via the ‘Save PDF’ action button.
