Tag: rill erosion

Although rills are small, they transport significant amounts of soil each year. Some estimates claim rill flow has a carrying capacity of nearly ten times that of non-rill, or interrill, areas. In a moderate rainfall, rill flow can carry rock fragments up to 9 cm in diameter downslope. In 1987, scientist J. Poesen conducted an experiment on the Huldenberg field in Belgium which revealed that during a moderate rainfall, rill erosion removed as much as 200 kg (in submerged weight) of rock.

Introduction to RUSLE2 – Applications for Construction Site Erosion Control

Do you know your RUSLE2?

Join Terry Toy and David Lightle as they discuss the Revised Universal Soil Loss Equation (RUSLE2) and how you can utilize RUSLE2 to estimate erosion on construction sites based upon the climate, soils, topography, surface cover, and management practices.

Erosion Control Methods for Steep Slopes (Part 2)

Erosion Control Methods for Steep Slopes (Part 2)

When sheet runoff from a major highway created gullies and rill erosion problems along Rutherford Road just east of Highway 27 near Vaughan, ON, aggressive erosion control methods were needed. Fortunately, the timing, along with a little help from Mother Nature, helped quickly stabilize a critical slope in in August

In most cases, it would be the rare day at work for employees to have to rappel down steep slopes to get to their job site. But that is exactly what Jerry Kallam, vice president of business and development at L&M Supply Co., encountered when he visited the Ecuador airport

The Measurable Parameters Behind Soil Conservation Methods

Before planning and implementing site-specific soil conservation methods, project designers, field specialists, and construction contractors should possess a basic understanding of the soil loss equation and its parameters, which author Linda Robinson explains in “Getting the Upper Hand on Sediment.” Launched as Part 1 (below) in a continuing series, our

Getting the Upper hand on Sediment

We live in a world of acronyms and equations. A world where letters are used for numbers and WOW upside-down is good old MOM. For instance, if the QSP or PE recommends HERO, he may inform the LRP. And that’s just the tip of the iceberg in the world of

Keeping the Dirt Where It Belongs

Consider the costly consequences at a 50-acre construction site for a commercial development in the Portland, OR metropolitan area this past fall, where attempts to protect bare slopes from the impact of winter rains and runoff was done the wrong way—using inappropriate and, in one situation, incorrectly installed best management

Studies in Compost

By Shelene Codner A two-year, $188,000 study conducted by Iowa State University’s (ISU) Agricultural and Biosystems Engineering Department concluded that blanket compost applications in large-scale construction projects have the potential to reduce runoff, minimize erosion, and inhibit weed growth along the state’s 100,000 mi. of roadway. Funded by the Iowa
