Determination of canal alignment earth work using Irregular Triangular Mesh

The earth work is usually regarded as one of the most expensive activities in engineering practice, yet the methods used in the consulting engineers do not provide the required accuracy and is very time consuming with regard to the computational time. In this paper a new method has been proposed for determining the earth work volume which was based on employing an irregular triangular mesh. The project line level is also optimized by using the method ofNewton-Raphson. Comparison between the results of the proposed method and the traditional one for a case having an analytical solution indicates that the proposed method improved the accuracy by a factor of 3. Therefore, applying the proposed method not only increases the accuracy of earth work volume computation, which directly influences the project expenditure, but also determines the optimum project line level based on the earth work volume.
