Artificial swales are often infiltration basins designed to manage water runoff, filter pollutants, and increase rainwater infiltration. The swale concept has also been popularized as a rainwater harvesting and soil conservation strategy by Bill Mollison, Geoff Lawton and other advocates of permaculture. In this context it usually refers to a water-harvesting ditch on contour. Another term used is contour bund. Natural swale Swales as used in permaculture are designed to slow and capture runoff by spreading it horizontally across the landscape (along an elevation contour line), facilitating runoff infiltration into the soil. This type of swale is created by digging a ditch on contour and piling the dirt on the downhill side of the ditch to create a berm. In arid climates, vegetation (existing or planted) along the swale can benefit from the concentration of runoff. Trees and shrubs along the swale can provide shade which decreases water evaporation, however they increase transpiration, so their net effect on the hydrologic cycle is probably to reduce infiltration. The term swale or “beach swale” is also used to describe long, narrow, usually shallow troughs between ridges or sandbars on a beach, that run parallel to the shoreline. https://en.wikipedia.org/wiki/Swale_(landform) HOW TO DIG SWALES: http://www.wikihow.com/Dig-Swales Lessons from a 100 Year Swale in a Cold Climate Arid Landscape

    Is the squash in the middle of the swale? Or on the uphill side?
