Frequently Asked Questions

How does stream erosion shape the landscape?

Flowing water, in streams and rivers or across the land in sheets, is the dominant erosional process in shaping Earth's landscape. ... Streams and rivers erode, transport sediment, change course, and flood their banks in natural and recurring patterns.

What causes the alteration of a riparian area?

Such alterations can result from dam construction, from transbasin diversions, or by water removal from rivers for irrigation or other consumptive uses, often in combination.

How are mountains and valleys affected by erosion?

Mountain ranges are built by forces within the Earth, but individual mountains are only the remnants left behind by the erosion of the valleys that separate them. Although hills and mountains are visually dominant, valleys are the active, evolving part of a landscape. Rivers do most of the erosional work of landscape shaping.

How are stream banks used to control erosion?

All stream bank stability methods focus on the boundary between the water and its channel banks. Structural and non-structural methods can be employed to control erosion. Some methods will improve the channel's ability to withstand greater boundary shear stresses such as vegetation, gabions or other forms of channel armor, while
