    Gabions are used to repair and reduce erosion in streams. The most common kind of gabion is made with rock rubble in a wire cage, but you can also use natural materials like brush from the surrounding landscape to build them. Gabions both slow and filter water as it passed through the spaces between the brush. Sediment is caught in the brush, which reinforces the gabion while filtering the water of materials that can cause increased erosion.
    It's important to select the right location for the gabion. The chosen site should be the lowest point of the main channel of the stream or river.
    When building the gabion, anchor the brush into the bank and make sure to pack the brush really tightly. Build gabions in the dry season, and if possible, learn from someone experienced the first time you build one. You can add rocks and rubble to the downstream side of the gabion as a buffer. You can build additional gabions downstream, too.

    The 8 Rainwater Harvesting Principles
    Every site is unique and much be approached with its own distinctive characteristics in mind. These are eight principles to utilize in conjunction with the permaculture principles and ethics when designing a rainwater harvesting system.
    Begin with long and thoughtful observation
    Sit quietly, listen with all of your senses
    Connect, think, imagine, plan
    Comprehend and copy nature
    Start at the top--or highpoint--of your watershed and work your way down
    Top of a roof or top of a mountain, for instance
    Start small and simple
    Human scale
    Technically and mechanically simple
    Multiple small earthworks are easier to create and capture more water than one big dam
    Spread and infiltrate the flow of water - slow it! spread it! sink it!
    Always plan for an overflow route and manage that overflow as a resource
    The overflow should be wide and flat to avoid erosion
    Maximize living and organic ground cover - create a living sponge
    Focus on perennials, shrubs, and deep rooted plants that can utilize and cover the saturated soil
    Maximize beneficial relationships and efficiency by stacking functions - do more than just harvest water
    Continually re-assess your system - feedback loop
    Observe, repair, improve, practice balanced maintenance, follow all of the principles together, celebrate abundance!
    Calculating Available Water from Roof Catchment
    A (ft²) x R (ft) = W (ft³)
    A: area of roof footprint in square feet
    R: rainfall in feet
    W: volume of water in cubic feet
    Note that 1 ft³ = ~ 7.5 gallons
    Rainwater Harvesting Containers
    Rainwater tanks should be shaded, painted, or otherwise covered to avoid plastic breakdown - growing plants on them can serve a dual purpose of shading/covering and producing something aesthetic and possibly edible
    If your roof is made of old asphalt shingles, the water captured from it should only be used for landscaping, not drinking
    Rainwater captured from tile or steel roofs should be okay for drinking
    You don't necessarily want the first rain of the season in your tank - anything that's accumulated on your roof since the prior rainy season will wash into your tank
    Design your system with a valve to shut off rainwater flow to your tank when you want to avoid runoff from the roof going into the tank - direct the overflow from this to somewhere specific in the landscape that is designed to accommodate it
    Be sure to include screens to prevent debris from going into the tank, and clean out gutters
    Tanks can be made of cement or can be designed in different shapes, such as a long, narrow fence that can serve dual purpose as fence and water catchment
