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.
