Down-cut
Explanation:
Lowering a streams base level will cause the stream to down-cut and erode to that level.
- The base level of a stream is the lowest level to which a stream can erode its channel.
- The base level of most streams is usually a function of their ability to down-cut their bed rock.
- Most streams have their base level equal to that of the sea level.
- When a stream downcuts to its base level, it becomes rejuvenated and gains more energy.
