A watershed is the area of land from which water drains into a river, stream, or other waterbody. Water flows from the land into a waterbody by way of rivers and streams, and underground through groundwater aquifers. The rivers and streams that flow into a larger waterbody are called tributaries.

A tributary is a freshwater stream that feeds into a larger stream, river or other body of water. The larger, or parent, river is called the mainstem. 6 – 12+

The place where a river enters a lake, larger river, or the ocean is called its mouth. River mouths are places of much activity. As a river flows, it picks up sediment from the river bed, eroding banks, and debris on the water.

Rivers of nearly every size have no affect on wind direction, however, the terrain that rivers lie within will affect swirling. Bill. How does a river (30 ft wide) effect your wind, scent? If set-up on a river, can you assume you will get a consistent wind.

In the upper course, the main work of the river is erosion.

The main function of the river in the middle course is transportation of sediments . It becomes a little slow and increases in volume . The major landforms formed by the river in this stage are flood plains , meanders , ox-bow lakes and braided rivers .

Answer. The volume of water in a river is at its greatest in the lower course. This is due to the contribution of water from tributaries. The river channel is deep and wide and the land around the river is flat.

Hint: A river has three basic functions: erosion, transportation and deposition. It is the combination of these three processes that lead to the formation of various landforms by the action of a river.
