Waterfalls and rapid
- Temporary features
- Can move and even disappear
a deep depression in a stream bed at the base of a waterfall or shut-in. It is created by the erosional forces of cascading water on the rocks at formation's base where the water impacts.
Rivers following a winding course
Steep bank formed along the outer portion of a meandering stream.
A depositional feature made of alluvium that accumulates on the inside bend of streams and rivers below the slip-off slope
A U-shaped lake that forms when a wide meander of a river is cut off, creating a free-standing body of water
Consists of multiple small, shallow channels that divide and recombine numerous times forming a pattern resembling the strands of a braid

- Deposit of sediments
Floodplains and terraces
- An area of low-lying ground adjacent to a river, formed mainly of river sediments and subject to flooding.
- Store when water is too much
- Floodplains are current flooded area
- Terraces are old floodplains
The process by which one stream captures the headwaters of another stream
An engineering technique to straighten, widen, deepen, or otherwise modify a natural stream channel.
- Graphs that show how a drainage basin responds to a period of rainfall. They are used to plan for flood situations and times of drought.
