tu madre.
The main parts of a river include a channel, in which the water flows, and a floodplain-a flat region of a valley on either side of the channel. Through the channel and floodplain, water and sediment-material transported by the river, such as sand and silt-are transferred from ridges and mountains to the sea or to a lake. A river starts on hillsides as small channels, or rills. The rills combine to make larger channels or tributaries that eventually come together, forming distinct streams. The largest channels formed by this convergence of tributaries are rivers, and they can carry large quantities of fresh water and sediment across continents.
Something big enough to be called a river can't start from a single well, it'll either come from a larger body of water - like a lake, or from several smaller streams convering into something that eventually becomes big enough to be called a river. In the latter case, deciding exactly where a river starts often get a bit difficult. Either way, it's usually referred to as the "source" of a river. Rivers usually end by emptying into another body of water. Either merging with another river, or draining into a lake, or the sea. Sometimes this is a fairly "clean" outlet, but if the land is very flat, the river can form a "delta" or an "estuary".
River efficiency is how easily a river can move water, sediment and bedload.
All rivers are by definition fresh water unless they are very polluted. There is, however, a portion of every river that reaches an ocean that is called an estuary. this is where the fresh water coming downstream mingles with the salty tidal water of the ocean.
Rio Grande in the USA, Rhine flowing through Europe for starters.
It's called the watershed.

I think you mean the source of a river, which is usually in the mountains.

Drainage basin :D Or watershed.
The area from which water drains into a river is called the river's watershed or drainage basin. It includes all the land and waterways that contribute runoff to that particular river system. Rainfall and other sources of water collect in the watershed, eventually flowing into the river and its tributaries.

The upper tributaries of a river are called headwater.
the main river and all of its tributaries are called a river system. The land drained by the river system is called a drainage basin. Drainage basins are separated by the high land in between, known as a divide or watershed.
