Image shown for entry if relevant and present

A narrow channel formed into a turf surface to aid the removal of surface water to sub-surface drains. The slit may be formed by excavating soil and filling with sand or sand overlaying gravel, or similar coarse aggregate material. It may even have sand injected into a channel without soil excavation.
