Whilst I'm doing the log roll I also hope to sort out the drainage problems
on part of the lawn. Part of this will be to put some topsoil down under
the turf to level it, but I also plan to help drainage by laying 2 strips of
gravel beneath the turf in the worst areas. Will this help - or would
another solution work better.

Mix some sand with the gravel, it helps a lot. keeps the
instersticies (sp?) open. I've used gravel drains to good effect.
I'd be tempted to use sand to raise the level too, rather than
topsoil.

Almost anything works - more elaborate schemes (porous pipes,
earthenware pipes, sumps, pumps etc) work better - you can complicate
the issue till the cows come home. The important thing is that
drainage needs somewhere to drain /to/.
