The ditch uphill of the bed will hold excess water and release it into the hugel bed, and you will have a source of dirt to pile atop your wood.
I live on a hill also and have dug several small swales to deal with the temporary streams that crop up in our (increasingly heavy) summer rainstorms. And at the bottom of the hill, also like David, I made a long hugel bed, probably about forty feet, which I did not dig at all. I just piled wood in a line and then buried it under massive amounts of dirt. I did not dig a ditch on the uphill side of it, because there would have been a lot of tree roots to deal with and I am lazy as hell. This will actually be my first season growing in that bed and I am excited to see how it works.
Good luck and post pics if you can.
