Ludi, thanks for the book links. I'll do a bit more research on the topic. What have you done over the years during times of flooding? Sandbagging the important areas and leaving everything else under floodwaters? Do you lose any trees, fences, and valuable topsoil each year in the flooded areas??
I would guess that especially in the first few years after moving in and planting trees that berming and adding lots of soil to the foot of trees would be quite the time-intensive activity. Just trying to figure out ways that a permaculture operation would be viable in such areas. Maybe all it is is embracing the floods, and mark the flood-prone areas on the property as pasture?
Anyone else cope with yearly floods, or frequent flash floods?
Half of Brisbane is built on a floodplain. It flooded 1974 and it flooded this year. A butcher took a photo of a bull shark in front of his shop 30 km inlands. Really I would never ever buy on a flood plain.
Tom, here's a video showing raised beds fit into odd shaped spaces, for growing in a wet climate: http://www.youtube.com/watch?v=ugFd1JdFaE0
