Meander bend on the River Conwy A B A cross section through a meander River Cliff FEATURE Slip off slope Erosion PROCESS Deposition Deep DEPTH Shallow Fast SPEED OF FLOW Slow CONCAVE CONVEX
What is a meander? (1 mark) Draw and label a cross-section from  A–B  through the meander (3marks) Explain how the features of a meander are formed (4 marks) A B River cliff Slip off slope
2007 Q2 (b) Explain why the meander cross-section has this shape ,[object Object],[object Object]
 
 
 
 
River features: Ox – bow lakes ,[object Object],Form from a meander, erosion on outside bend especially by hydraulic power , deposition on inside bends where water is shallower and lower velocity, neck narrows, breaks through in time of flood  deposition seals ox bow lake. eventual loss of lake to form meander scar.
