Preventing Erosion. A crucial role of sustainable sites is to reduce erosion, the physical wear of soil and surface rocks by water and wind. Eroded soil, called sediment, is the number one pollutant of our waterways. By taking measures to prevent erosion on your property, you can help alleviate a host of problems caused by erosion in manmade ...

What is Erosion? Effects of Soil Erosion and Land Degradation

These are very real and at times severe issues. The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Sedimentation and Erosion

Sedimentation and erosion actively shape Yellowstone's landscape. Here, the Lamar River erodes its banks, depositing the sediment elsewhere. Not all the rocks in Yellowstone are of "recent" volcanic origin. Precambrian igneous and metamorphic rock in the northeastern portion of the park and Beartooth Plateau are at least 2.7 billion years ...
