Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles. For example, silt falls out of suspension via sedimentation and forms soil (some of which may eventually become sedimentary rock).

Geosynthetics for Roadway Construction

Geosynthetics for Roadway Construction

Ever since the Romans used palm fronds and other plant fiber matting to reinforce the sub-bases of their famous roads, fabrics have been used to improve road longevity and performance. Modern road construction methods rely on a family of materials called geosynthetics to achieve the same results. But these more sophisticated materials can

Three Minutes With John Deere CEO Sam Allen

John Deere & Company was founded in 1837 with a polished-steel plow. In 1918, the company bought the maker of Waterloo Boy tractors, and the tractor became Deere’s basic product. Nearly 100 years later, John Deere celebrated its 175th anniversary in 2012 with net sales and revenue of more than

“Closed Indefinitely”

“Closed Indefinitely”

A co-worker came into my office this morning to tell me about the trip he almost-but-not-quite took to Big Sur last weekend. Big Sur is a scenic area on California’s central coast, popular with tourists and locals alike. One way to get there is—or at least, was—to take Highway 1.

Smart Irrigation Reduces Nitrogen Leaching

Smart Irrigation Reduces Nitrogen Leaching

While nitrogen is critical for agricultural production, too much nitrogen can negatively affect health and the environment. Ironically, excess nitrogen can even produce a harmful effect on crop yield, as well as native species and biodiversity.

A report from the Agricultural Sustainability Institute at the University of California, Davis, published by

Pipe Inspection and Repair

Pipe Inspection and Repair

A recent California Department of Transportation (Caltrans) stormwater pipe repair project his company executed in California symbolizes two issues faced nationwide in drainage pipe and repair, points out Scott Odell of Michels Pipe Services.

Tiny, Long-Distance Travelers

Tiny, Long-Distance Travelers

We’ve written in Erosion Control magazine for years about the problem of airborne dust, and even the ways in which distant events—a sandstorm in the Sahara Desert, say—can deposit sediment particles thousands of miles away. A new study shows that the long-distance air-quality problem might be more widespread than previously
