Contour sills, a possible alternative to contour bank systems, are not yet a recommended practice but have been under investigation in the Department for three years.
The sills were originated by Mr. B. a'B. Marsh an adviser with the Soils Division's Soil Conservation Service Branch.
The sills were designed to avoid some of the problems associated with contour bank systems and are considered to have potential on mildly eroded areas with moderate to gentle slopes, particularly where water disposal problems arise.
