Keyline Design - Application

Application

P. A. Yeomans published the first book on Keyline in 1954. Yeomans described a system of amplified contour ripping to control rainfall run off and enable fast flood irrigation of undulating land without the need for terracing.

Keyline Designs include irrigation dams equipped with through-the-wall Lockpipe systems to gravity feed irrigation, stock water and yard water. Graded earth channels may be interlinked to broaden the catchment areas of high dams, conserve the height of water and transfer rainfall run-off into the most efficient high dam sites. Roads follow both ridge lines and water channels to provide easier movement across the land.

Famous quotes containing the word application:

    “I think that a young state, like a young virgin, should modestly stay at home, and wait the application of suitors for an alliance with her; and not run about offering her amity to all the world; and hazarding their refusal.... Our virgin is a jolly one; and tho at present not very rich, will in time be a great fortune, and where she has a favorable predisposition, it seems to me well worth cultivating.”
    —Benjamin Franklin (1706–1790)

    ““Five o’clock tea” is a phrase our “rude forefathers,” even of the last generation, would scarcely have understood, so completely is it a thing of to-day; and yet, so rapid is the March of the Mind, it has already risen into a national institution, and rivals, in its universal application to all ranks and ages, and as a specific for “all the ills that flesh is heir to,” the glorious Magna Charta.”
    —Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)

    “Great abilites are not requisite for an Historian; for in historical composition, all the greatest powers of the human mind are quiescent. He has facts ready to his hand; so there is no exercise of invention. Imagination is not required in any degree; only about as much as is used in the lowest kinds of poetry. Some penetration, accuracy, and colouring, will fit a man for the task, if he can give the application which is necessary.”
    —Samuel Johnson (1709–1784)
