Would it help if rivers were dredged? They nust silt up over the years and
then when there is a high rainfall they don't have the capacity. The
solution always seems to be based around raising the banks.

Neither is a good solution. Both hurry the water downstream and that makes
flooding worse. The best idea is to trap the water as far upstream as possible
and let it trickle out slowly. River dredging, bank heightening, bank
strengthening, and river straightening are all counter-productive as they all
require future intervention.
Of course trapping the water up stream also requires constant intervention but
that can be done free of charge as long as you get the right workforce* on the
job.

Of course it also means that you cannot build on the floodplain unless you're
building higher than likely future floods.
