The objectives of erosion control are stated, the mechanism of erosion is described, a way of quantifying erodibility of a site is outlined, and the factors which influence the rate of erosion of a slope are reviewed. Comments are made on the quantification of the soil erodibility factor and on practices which assist conservation. These practices include contour ridging, light scarificaton, serrations or stepping strip sodding, slope fascines (temporary stabilizaton with brushwood), rip rap, soil-cement stabilization, and benches. The latter have been successfully used in laterised soils where slopes of between 5 in 1 and vertical have been safely formed. Crest interceptor ditches may be used to prevent surface runoff from rising ground behind a slope from running down the slope. For the purpose of reducing sheet erosion of embankment slopes, a sand asphalt dyke may be constructed on the edge of highway shoulders. The use of grass and legumes to reduce slope erosion is described, and its effectiveness is discussed. The provision of instant cover is discussed, and the results are presented of a study of stone and wood-ship mulches for erosion control on construction sites. The design and protection of roadside ditches, and the protection of shoulders from rain and traffic erosion are also covered.
