Keyline Design at the Beach by Darren Doherty (videos)

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
