    when should contour swales be used and when should keyline be used?

    I've only heard some brief suggestions, but maybe someone has this figured out. Any scientific approached with side by side systems?

    i'm getting rusty now, but the differences are that keyline is set up
    to actively move water away from the places it wants to gather
    so you are designing to use gravity to disperse the water across
    as large an area as possible.

    swales by contrast are usually not used to move water that often
    but to hold it in place.

    both have their uses. i'm sure you could combine them if needed.
