| watershed |
The area of land from which rainfall (and/or snow melt) drains into a single point. Watersheds are also sometimes referred to as drainage basins or drainage areas. Ridges of higher ground generally form the boundaries between watersheds. At these boundaries, rain falling on one side flows toward the low point of one watershed, while rain falling on the other side of the boundary flows toward the low point of a different watershed.

any of several areas over the convexities of the cerebral or cerebellar hemispheres, distant from the circle of Willis, where the vascular beds of two cerebral arteries meet and form anastomoses. At times of prolonged systemic hypotension, these are particularly susceptible to infarction, with those fed by the largest arterial branches being the first affected. See also watershed infarction, under infarction.
