Erosion and Sedimentation
Erosion and Sedimentation. Erosion in the context of soil and watershed conservation is the detachment and movement of soil particles by natural forces, primarily water and wind. More broadly, erosion is the process of wearing away rocks, geologic, and soil material via water, wind, or ice (e.g., glaciers).

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.

The Causes and Effects of Soil Erosion, and How to Prevent It
Another study showed that soil erosion in Sleman, a district located in Java, costs 17% of an average farmer's net income per hectare of agricultural land. The U.S. agricultural sector loses about $44 billion per year from erosion. This value includes lost productivity, along with sedimentation and water pollution.

Importance of Erosion and Sedimentation to Water Quality
Damage to water quality occurs when this eroded soil enters surface waters. Sedimentation occurs when water carrying eroded soil particles slows long enough to allow the particles to settle out. The smaller the particle, the longer it stays in suspension. Larger, heavier particles such as gravel and sand settle out sooner than smaller, lighter ...
