Darren Doherty, principal of Australia Felix Permaculture, builds a scale model watershed to explain how water cycles through the landscape in a sequence of natural patterns.
Part One introduces the Order of Drainage and identifies the keypoint of a valley.
Part Two - effects of deforestation and hydroelectric dam siting - succession of ridges - keypoint ponds and irrigation of foothills
Part Three - saddle ponds and slope irrigation
Part Four - reforestation and restoring the landscape
Part Five - rainwater vs. groundwater - drought and fire proofing
