The network of rills, gullies, streams, and rivers in an area is often referred to as a watershed or river basin. This system of interconnected waterways ultimately drains into a common body of water, such as a lake or ocean.
An example of a watershed is the Mississippi River watershed, which drains water from 31 U.S. states and two Canadian provinces into the Gulf of Mexico.
The Orinoco watershed - its basin, covers an area of about 990000 km2
A watershed is an area of land where all the water drains into a common outlet, such as a stream, river, or lake. It is defined by the topography of the land, with higher elevations forming the boundaries of the watershed. The physical characteristics of a watershed can include its size, shape, slope, soil type, vegetation cover, and land use activities.
The Susquehanna River is the largest river that flows into the Chesapeake Bay, contributing a significant amount of fresh water to the bay's ecosystem.

A nested watershed is simply a watershed within a watershed. An example might be the Platte River watershed which is a nested watershed within the Missouri River watershed which in turn is nested within the Mississippi River watershed.
