Erosion and Sediment Control Tip #102

 


Here’s a picture of a silt fence that serves no purpose.  My guess, it was probably installed where identified in the project plans.

If a silt fence is not ponding water, it can’t capture coarse soil particles in the runoff.  A silt fence requires proper design to contain its drainage area design storm runoff, proper location on the job site, proper off-set installation, and routine maintenance to be effective in capturing coarse sediment.

Today’s Erosion and Sediment Control Tip: #2

Image
In order to control erosion on a construction site, you must first understand the erosion process. Rainfall and the surface runoff of rainfall produces four main types of erosion on a construction site: Splash Erosion occurs when the raindrop impacts the bare soil surface and dislodges soil particles. Sheet Erosion occurs either after the surface of the soil is saturated or the rainfall exceeds the infiltration rate of the soil. Then the soil detached by splash erosion and the additional soil particles detached by runoff/overland flow move downslope. (Note: Splash and Sheet are sometimes referred to as Interrill Erosion ) Rill Erosion occurs when the sheet flow concentrates and causes small rills (about 1 inch deep) further eroding the soil surface. Gully Erosion occurs when runoff water in a rill detaches more soil and deepens and/or widens the channel to a significant size.  (Note: There is no universally recognized dep...

Partnership in Action: Tuscaloosa County SWCD and NRCS Host State FFA Land Judging Event

Image
2025 State Land Judging Contestants Tuscaloosa County Soil and Water Conservation District NRCS Alabama Alabama’s Soil and Water Conservation Districts (SWCDs) and USDA Natural Resources Conservation Service (NRCS) have a long tradition of supporting FFA land judging—a hands-on competition that teaches students about soil, conservation, and land use. This year, Tuscaloosa County SWCD led efforts to host the 2025 Alabama State Land Judging Competition at the Tuscaloosa County School System Agriscience Teaching Farm. “We were thrilled when NRCS approached us about hosting,” said Dupree Galloway, Chairman of the Tuscaloosa County SWCD. “Supporting land judging helps us build stronger connections with local schools and students. It’s a natural extension of our mission to promote conservation education and youth engagement.” Tuscaloosa County SWCD coordinated the event —securing a site with diverse soils, ensuring the pits were dug, and managing logistics. They worked closely with partn...

Erosion and Sediment Control Tip #90

  A reminder that when the soil is covered, erosion is prevented.   GREEN IS GOOD.  Keep vegetation if it doesn’t have to be cleared and create vegetative cover at every opportunity on a construction site.    ______________________________________ Have you registered for Clear Water Alabama?   https://alabamasoilandwater.gov/alesc-clearwater/     Perry L Oakes, PE Program Coordinator AL Erosion and Sediment Control Program
