Etymology: "Waterbars" is the plural of "waterbar," a compound of "water" and "bar." The "bar" here is the ordinary sense of a barrier or obstruction, so the word describes something placed across a path to stop a flow. On a sloping road or trail, a waterbar is a shallow ridge or diagonal bank of earth, sometimes reinforced with logs, rock, or gravel, built at an angle across the surface. It catches runoff and diverts it off the track before the water can gather speed, cut gullies, and carry soil away. The name is a transparent piece of plain English rather than a borrowing or a coinage from another language, so the most useful way to read it is literally: a bar that stops water. The same idea lies behind the older engineering term "water bar" as a separate noun, and the two-word and one-word spellings are both found in practice.
