13.3 V shape As they grow they become U shaped How do rivers begin?

Headward erosion When land is worn away at the head of a stream or gully

Base level A stream cannot erode any lower than the body of water into which it flows

Stream piracy One stream or river takes over another

waterfalls Lets talk about recession and undermining…

`

13.4 Floodplains Floodplain FERTILE! Where the river water goes when a river floods

meander

Oxbow lake

` Natural levee

Floods 2 types….. Flash flood Large River Floods

Flood prevention and control
