Abstract
A method and apparatus of forming two or more waving rip lines across a sloping surface, wherein the rip lines are formed at substantially right angles to the downward direction of the sloping surface and have a plurality of peaks and troughs. The troughs form catchment areas for water and the peaks separate the troughs limiting the amount of water stored in the catchment areas. Each of the rip lines can be substantially parallel with each other or offset relative to an adjacent rip line. The plurality of waving rip lines contribute to the stability of the landform, long term conservation and maintenance of the landform, and thereby encourage establishment and growth of vegetation in the remediation process.
Claims15
An apparatus to form rip lines across a sloping surface, comprising two or more tines spaced apart from each other;
- a linkage arrangement to move the tines laterally relative to a forward operational direction of the apparatus;
- and
- a control system to actuate the linkage arrangement in accordance with programmed instructions and position information to form regular rip lines with a predetermined wavelength;
- wherein during operation the tines move laterally in a predetermined manner to form waving rip lines across the sloping surface;
- wherein a wavelength and an amplitude of the rip lines are determined by the sloping surface and associated topography and the material of the sloping surface.
A method of forming two or more waving rip lines across a sloping surface comprising,
- providing an apparatus to form rip lines across a sloping surface, comprising
- two or more tines spaced apart from each other;
- a linkage arrangement to move the tines laterally relative to a forward operational direction of the apparatus;
- and
- a control system to actuate the linkage arrangement in accordance with programmed instructions and position information to form regular rip lines with a predetermined wavelength;
- wherein during operation the tines move laterally in a predetermined manner to form waving rip lines across the sloping surface;
- and
- forming the rip lines at right angles to a downward direction of the sloping surface and have a plurality of peaks and troughs, said troughs form catchment areas for water and the peaks separate the troughs limiting the amount of water stored in the catchment areas;
- each of said rip lines can be parallel with each other or offset relative to an adjacent rip line;
- wherein a wavelength and an amplitude of the rip lines are determined by the sloping surface and associated topography and the material of the sloping surface.
