A Research on the Usage of Least Squares Land Grading Design Method in Microsoft Excel

Öz

The possibilities of automatic land grading design for the regular shaped (rectangular) fields using the Microsoft Excel 2010 with the least squares technique, have been investigated in this research. When the original level rod and area weighting factor at each grid point of field are entered, the program automatically performs the land grading design for the field in a very short time in contrast to the long calculations required for the conventional method. The cut or fill depths at each grid point, the grading type, the cut-fill volume distribution plan, and three-dimensional perspective views of the field before and after grading were given as the results of the design. The Microsoft Excel program developed with this study can be used for the fields formed with 10 rows by 10 columns with variable grid sizes. The developed program was applied to two different textbook examples, the same results were obtained.
