The volume of water that flows through a stream or river in a specific amount of time (measured in volume/time).
The material carried by a river or stream.

An area of land that drains into a river or lake.

Process in which sediment is laid down in new locations.

Processes by which rock, sand, and soil are broken down and carried away (i.e. weathering, glaciation)
A crescent-shaped lake that is formed when a meander of a river is cut off from the main channel.
These include marshes, swamps, estuaries, and bogs; these are ecosystems which have standing water for large parts of the year.
