Sheetflow Erosion & Sediment Control Heavy Civil Construction

Check Dam Installation Example

Check dams need to be installed so that the center point of the dam is at least 8 inches lower than the outside edges; 12 inches in areas where intense rainfall occurs. If the center point is higher than the outer edges, water will run around the dam and erode the side slopes of the ditch, causing erosion. See Video.
