Watershed
Watershed explained in an easy to understand way:
Imagine trying to gather all the toys scattered around your living room into a single toy box. Just like how you need to collect each toy and bring it to one central location, a watershed functions by collecting all the water from the surrounding land area and channeling it into a river system. In this analogy, the toys represent water from different parts of the land, the living room is the watershed, and the toy box is the river system where everything ultimately converges.
