Rejuvenation

Rejuvenation

A fall in sea level relative to the level of the land, or a rise of the land relative to the level of the sea, enables a river to revive its erosional activity

Knickpoints

Breaks in gradient along the long profile of a river, usually marked by rapids or a waterfall

River terraces

The remnants of the former floodplain prior to rejuvenation

Incised meanders

Deeply cut into the landscaped and marked by cliff-;ike banks on either side of the channel

Ingrown meander

Occurs when the uplift of the land or incision occurs slowly, allowing lateral erosion to take place, creating an asymmetrical valley cross profile

Entrenched meander

Occurs when uplift is more rapid, a symmetrically shaped cross profile is created
