Straw Wattles Reduce Erosion on Slopes

Filed under: Video — Sheetflow @ 7:04 am

As water runs down a slope, it starts as sheetflow. If left unchecked, the water picks up velocity and erodes, forming small channels called rills. If the rills are left unchecked and the water flow continues to increase in velocity as it runs down the slope, it begins to form gullies. At this point, significant erosion is occurring. Straw wattles placed on a slope, on contours and at regular intervals, will intercept flowing water, reducing its velocity and reducing erosion. Straw Wattle Installation Drawing
