WebAs the stream becomes larger, it widens and allochth-onous input decreases. But as it widens, riparian shading decreases and autochthonous inputs increase. The result is a U-shaped curve of energy input. Exceptions to this pattern (e.g., Winterbourn 1981) include streams that begin in grasslands or deserts or where desert streams lose flow ...

This guidance sets out the basis on which the Environment Agency should decide whether or not a river or watercourse is treated as a ‘main river’. Main rivers are usually larger ... WebThe widening of rivers downstream is a natural phenomenon caused by the decrease in the gradient of the river channel. This gradient, or the slope of the river, plays a critical role in the river’s flow velocity and erosive power. As the river travels downstream, it loses elevation at a slower rate, leading to this decline in gradient. steel fabricators north brisbane
