25: Erosion and deposition on a meander

Using the diagram above, complete the following questions:

1) Draw an arrow and label the outside bend of a meander.

2) Draw an arrow and label the inside bend of a meander.

3) Draw a red dashed arrow -----> to show where you think the fastest flow of water would be found on a meander.

4) Draw an arrow and label an area where erosion might occur on one meander.

5) What type of erosion do you think is happening on the meander?

6) Why do you think erosion is occurring on this part of the meander?

7) Draw an arrow and label an area where deposition might occur on one meander.

8) What type of material / sediment do you think is being deposited?

9) Why do you think this type of sediment is being deposited?

10) What things do you think might change the flow of water on a meander? For example, would a big boulder on the outside bend make the water flow faster in the centre of the river?

11) Look at the photo below. Label the evidence of erosion and deposition on these meanders.

Also, label the inside and outside bends of the meanders.
