Tag: clay soils

Clay is a fine-grained natural rock or soil material that combines one or more clay minerals with traces of metal oxides and organic matter. Clays are plastic due to their water content and become hard, brittle and non–plastic upon drying or firing.

Heavy Duty Cycle

Industry innovations often arise from the people whose everyday work poses a frustrating obstacle. “If we could only do…” or “If there was just a machine that did…think how much better our work product could be!”

Marshalling ideas plus experience and faced with the growing dilemma of keeping equipment clean, Garrett

How to be Defense-minded With Trenching and Shoring Projects

How to be Defense-minded With Trenching and Shoring Projects

Trenching operations are never “ordinary.” Accidents are never expected. But they can be anticipated and prevented. To be forewarned is to be forearmed. Geotechnical investigation of the soil to be excavated during the trenching operation provides the first warnings that there could be a problem with trench stability. Engineering analysis

Stormwater Infiltration in Clay Soils

Stormwater Infiltration in Clay Soils

Stormwater runoff from impervious surfaces is causing devastating effects on the landscape of our developing watersheds. We are disrupting the natural hydrological cycle that supports our potable water supplies and natural fauna. Intentional stormwater infiltration can restore that cycle. However, the lack of awareness and the perceived lack of data

Twenty-Year Engineering Assessment of an LID Facility in Boulder, CO

This article provides a summary of the evolution of small stormwater control facilities constructed approximately 20 years ago using low impact development (LID) principles at a 10,000-square-foot office site in Boulder, CO. This project was undertaken to demonstrate how surface stormwater controls designed as multifunctional systems can support regionally appropriate

Dirt: The Good and the Bad

Dirt: The Good and the Bad

Dirt, soil, seed support media: the material goes by lots of names. As kids, we play in it and track it onto our mothers’ clean floors. As erosion control specialists, we sometimes see it as a nuisance that must be contained or glued down. In revegetation projects, growth is the

Transforming Springfield’s Mill Race Into a Community Asset

Transforming Springfield’s Mill Race Into a Community Asset

The Mill Race Stormwater Facility, one of the largest regional water quality treatment ponds in the city of Springfield, OR, includes a vegetated drainage swale, trailhead, and a multi-use path enhancing the historic Mill Race for recreational values and wildlife habitat. The project included the involvement of multi-disciplinary local agencies

College Stormwater Programs

College Stormwater Programs

Not too long ago, there were only two colleges in the United States where one could learn about stormwater management, notes Brant Keller, public works director for Griffin, GA.
