Meander bend on the River Conwy

1. The River Conwy has deposited material in this section of its course. Suggest reasons why this has happened.

2. Meander bend on the River Conwy A B Explain why there is more deposition at ‘A’ rather than at ‘B’.

3. The meander from above. E E D D D D E E E E D D D D E E

4. Formation of a meander Task: Draw and explain in your own words how a meander forms by erosion and deposition.

5. This is a cross section of a meander bend. Where would the following go? river cliff fastest velocity slip off slope undercutting area of deposition

6. Oxbow lakes

7. On this meander bend where would you label the line of highest velocity?

8. Draw these four diagrams in the correct order of oxbow lake formation. Then match 3 of the diagrams with the most appropriate explanation from ‘A’, ‘B’ and ‘C’. 2. 3. 4. X =erosion on the outside of the meander bend 1. X X X X X A. The river floods and erodes through the thin meander neck. The river now takes the easier, straight course. The meander loop is left as an oxbow lake. B. The fastest flow is on the outside bend of the meander. This fast current erodes the meander neck through the processes of erosion. C. The meander neck is further eroded until only a thin piece of land separates the two channels.
