Swales and Keyline

Swales on contour and keyline layouts are earthworks designed to intercept rainfall and distribute it slowly across a slope rather than letting it sheet off. These articles cover how to survey and mark contour lines, keyline plow patterns, swale sizing for catchment area, overflow spillway design, and the soil-moisture and pasture-recovery changes documented after earthworks are installed.
