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. WebExplain. Flow velocity is usually greater at the mouth of the stream than the head of the stream due to an increase in channel size, an increase in channel discharge, and a decrease in channel roughness near the mouth.

WebDec 16, 2024 · Meanders and their importance to soil erosion and transport Rivers are constantly changing their course, meandering through time and space, forming new features and erasing old ones.
