These answers should only be consulted after you have made your best attempt at the questions.
It will do you very little good just to copy these out without having given the questions your 'best shot'.
A1.
a. flat floodplain
b. presence of ox - bow lakes
c. meandering river
d. gentle river gradient
e. gentle valley slopes
A2
a. narrow river
b. narrow floodplain
c. valley sides are too high
d. meanders are too small
A3
a. they could measure river depth along the
line A - B every so often (e.g. metre) this would give them an
accurate cross section of the river at this point.
b. they could use floats to measure the speed of the river at
the inside and outside of the bend to see if water flows faster
on the outside of a meander.
c. they cold photograph / sketch the slopes on the inside and
outside of the meander to show the contrast between the erosion
(river cliff) and deposition slopes (see Diagram2.6g).
d. they could measure river width at several points to see if
the river became wider as it flowed downstream or if it was wider
on a straight section or a meander.
A4
a. erosion takes place on the outside of a
bend where the river speed is fastest. The bank of the river
is undercut and the river is deepest at this point.
b. deposition takes place on the inside of a bend where the
river speed is slowest and it is less able to carry its load.
The river is shallowest at this point.
