A Simple Method for Land Grading Computations and its Comparison with Genetic Algorithm (GA) Method

Abstract

This paper reports the development of a new method for land grading computation having time saving and simplicity advantages. The conventional method uses the trial and error process to determine the desired cut-fill ratio, which is cumbersome and time-consuming. In developed method, the trial and error process is not necessary. Instead, the Excel Solver was applied to determine the plane equation of land grading, and minimize the earthwork volume based on a desirable cut-fill ratio. Then, results of the new method for three data sets were compared with the conventional and genetic algorithm (GA) methods. In all of the data sets, results of the new method were better than two other methods. The cut-to-fill ratio and cut volume were less in new method than others.

Using of Best Plane Method (B.P.M.) to Estimate the Optimum Number with Value and Direction of Slopes for Farm Units in Irrigation Project

“…This leveling may only be necessary for several sprinkler irrigation systems, but it does not fulfill which means the inaccurate leveling, the purpose of the methods of surface irrigation and the reason is that most of requiring a careful leveling of the land [3]. About leveling and grading operations that use surface irrigation methods [4], the land must be divided into farms, and then the surveys and design levels for the grading work will then be installed. As the second part of process is the land reclamation process, it includes designing and implementing farm drains, and then the agricultural land becomes ready for the process of leaching the soil and rid it of salts.…”
