Volume equalization method for land grading design: variable sloped grading in one direction at rectangular fields

This paper presents the principles of a new method for variable sloped grading in one direction that is adapted from Ayranci and Temizel (2011) which has been developed to perform land grading design for uniform sloped grading in one direction. The main goal of this method is to minimize the volumes of earth work required for acceptable smooth surface. The method based on the assumption that the before and after grading the soil volumes measured from a reference elevation are equal. The method eliminates the need for trial and error procedures. According to the results of the application of the complete design procedure to a hypothetical area about 2.21 ha, the method is accurate in rectangular fields.
