Explanation / Answer
Wateshed boundaries are defined by topographic divides and delineate areas where surface water runoff drains into a common surface water body, such as lake or section of a stream. Watershed boundaries are called drainage divides. They are typically areas of high relief like mountains or hills. Water falling on one side of the divide flows into one watershed and water on other side of the divide flows into a different watershed.
