Streams and Rivers.

A river system is made up of a main stream and tributaries – Tributary: a stream that flows into a lake or into a larger stream.

Transpiration Similar to evaporation, this is the loss of water through plants. – Pores in leaves (stomata) are opened to release oxygen and water vapor.

Presentation transcript:

What actually happen in Boscatle Once you have decided what should happen at Boscastle… lets see what actually happened

Embankments (on outside of meander)

2. Replaced low foot bridge

3.Channel enlargement

4. Flood Warning system Argonaut monitors the flow of the rivers entering the town

5. Land use zoning The loss of cars is less dangerous than the loss of houses!

6. Washlands See if you can spot the washlands on the map !

Should humans try to manage rivers … or do we make it worse Should humans try to manage rivers … or do we make it worse? What do you think?

What are the benefits of natural flooding Or Which is better?

Benefits to people Silt deposited on floodplain - Replenishes drinking water - Slows velocity -

Benefits to the environment Fish can breed - Bring relief to drought in dry areas-
