The invention is directed to 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.
A method 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, said troughs form catchment areas for water and the peaks separate the troughs limiting the amount of water stored in the catchment areas;
A method as claimed in any one of the above mentioned claims, wherein each of the rip lines are offset relative to an adjacent rip line so that water can be diverted to a preferred trough.
A method as claimed in any one of the above mentioned claims, wherein one or more of the peaks are shaped unsymmetrically, pointed, round or flat to facilitate the diverting of water, topography changes or accommodating differences in material.
A method as claimed in any one of the above mentioned claims, wherein one or more troughs have a different shape to provide a catchment area that holds a different volume of water.
A method as claimed in any one of the above mentioned claims, wherein the wavelength and amplitude of the waving rip line are substantially constant along each of the rip lines.
A method as claimed in any one of the above mentioned claims, wherein the length of the wavelength is relatively shorter and or the amplitude is relatively smaller when the sloping surface is concave or convex in a direction that is substantially at right angles to the direction of the slope.
A remediation process to restore an earth waste dump using the method as claimed in any one of the abovementioned claims.
A stable landform that is formed using the method of any one of the abovementioned claims.
An apparatus to form rip lines across a sloping surface, including
