Eyebrow terraces are a form of micro catchment water harvesting system. They are handmade micro basins, in the shape of an eyebrow, and often made from gabion baskets lined with geotextile drainage membrane.
Their main goal is to collect runoff water from a small catchment area and infiltrate it into the soil. This way, it is stored in the root zone and will be available for vegetation and crops.
They are usually situated on hillsides and they can be used on slopes of up to 50%. The steeper the slope, the more wire baskets lined with geotextile drainage membrane.
Eyebrow terraces on steep slopes, reinforced with wire baskets filled with gabion stone, are resistant to the increased water speed, caused by the slope. Unlike some other forms of terracing, eyebrow terraces are not uninterrupted. Instead, they can be some meters apart. After completion, the pit uphill from the eyebrow may fill with sediments and soil and thereby terraces arise
