Tag: check dam

A check dam is a small, sometimes temporary, dam constructed across a swale, drainage ditch, or waterway to counteract erosion by reducing water flow velocity. Check dams themselves are not a type of new technology; rather, they are an ancient technique dating all the way back to the second century A.D. Check dams are typically, though not always, implemented as a system of several check dams situated at regular intervals across the area of interest.

Integrating Land-Use Changes for Future Stormwater Projects

In early July 2013, 2 inches of rain fell within a 45-minute period at the city-owned Lebanon Municipal Airport in Lebanon, NH. This storm created devastation for the city and the airport, with multiple slope failures and roadway washouts. In all, 3.47 inches of rain fell during the 10-year storm

“There are three reasons for us to do a stormwater project. One is to fix a flooding problem. Nine out of ten citizens would say this is the main reason. Two is to improve water quality,” says Dave Mayes, Stormwater Services Division manager for the city of Wilmington, NC.

Hydroseeding: Protecting the Soil and the Future

Hydroseeding: Protecting the Soil and the Future

Timing hydroseeding correctly requires balance and planning. Today, contractors like Brian Young, general manager of Fox Erosion Control & Landscape Inc. based in Clackamas, OR, are fast approaching the last seeding window of the year as set for his region by the Oregon Department of Transportation: September 1 through October

Putting the Brakes on Silt – Part 2

“For years, a crew would have to come out to a job site and install SiltSoxx in the field with big blower trucks,” says Zock. “Some people didn’t like that, and sometimes it was hard to get scheduled. That’s all changed.”

Filtrexx still has professionally certified teams all over the United

Inlet Protection During Construction—and After

Inlet Protection During Construction—and After

Water—a simple molecule of one oxygen and two hydrogens, with such a simple design. It’s the very structure of water that makes it strong enough to force boulders loose on a hillside. By water’s polarity, water molecules attract more water molecules and soon the long branched “polymers” are strong enough

Silt Stalkings

With construction’s high cost of equipment, fuel, and labor, it’s too bad we can’t harness the power of water. It often seems that nothing can move soil faster than a good rain-unfortunately, not necessarily to the places you want it to go. Therefore, soil and sediment must be captured and

Road Control

Road Control

On highways under construction and those being repaired throughout North America, the challenge for contractors is to come up with effective methods for erosion and sediment control. Common challenges include working around traffic-which sometimes means working during non-peak hours or at night-protecting existing inlets and catch basins along the roadways,

New Angle(s) on Sediment Control

When the Tennessee Department of Transportation decided to improve a 4-mile stretch of Interstate 65, project manager Todd Cheek of Mid-TN Erosion was called in to assist with sediment control issues. As he describes the project, “It is the grading, drainage, and construction of a concrete I-beam bridge, a concrete
