Developing and Testing a New Method of Land Leveling for the Sites of Irrigation Projects

Abstract

Any new engineering project almost needs for land grading computations and design.
Many methods of computation, some are traditional and other has been recently developed,
are already in use. However, there is no one simple method which satisfy the special cases
that may be experienced, e.g., in irrigation engineering and site preparing of large
hydraulic structures, a method that may enable the user to select the most economical stage
of grading complying with his own case study.
In this research a new method of gradually step by step land grading procedure has
been proposed. The method is very simple, reliable and permits economical choices of
solution.
The procedure is based on relaxation technique of gradually grading of the land
under work, that is, by cutting benches and filling pans that following the computed
general slope of the whole area. By this procedure the land grading shall be graded gradually towards a horizontal plane of zero slopes in all directions, however, the user may
select any suitable stage of grading that satisfy his case of design.
The proposed grading method has been well explained through an explanatory
example. The results showed that the method can be easily programmed for computer,
provides several economical choices for the user, save efforts and money in using grading
machines, and no limitations are needed in using the method.
