Hi Mark and welcome to Permies:
As for a definitive book - there's not one....yet. However, there are resources.
I would start with Brad Lancaster's books, "
Water Harvesting for Drylands and Beyond, Vol 1 and 2" (there will be a third volume out next year - that one will be about water storage in various vessels). Volume 1 has been translated into Arabic. Geoff Lawton often references Brad's work and I know the "Greening the Desert" project in Jordan is already in possession of some of the Arabic volumes.
Then I would go to permaculture global and read anything you can about the various dryland projects there and print them out if you can. I need to compile this list for my own purposes, so after I'm done (probably take a few days to find and order all the information) I'll also post that info here. Here are a couple recent posts for starters.
