Abstract: The present paper focuses on the point irrigation design for crops and growing vegetables on an experimental area 2432 m2 at Buchel locality, Northern part of Gobi desert in Mongolia. An underground water source (drill hole - well capacity 2 l/s with water temperature 10°C) and electricity were available in the locality of the selected area of 1 ha and 0.2% grade of slope (no map was available). The design of the surface and subsurface point irrigation for an area of 128 m2 is shown together with a brief description of the hydraulic materials used for the development of the original HYBOZAM program, which was programmed in Microsoft Excel editor, especially to design the pipe dimensions of the point irrigation. A combination of two plastic pipes (with diameters 35.4/40 mm and 28.2/32 mm and 20 m lengths each) was used to provide suitable irrigation uniformity from the orifices on the laterals. HYBOZAM program provides a visual evaluation of the discharge distribution uniformity from the orifices on the laterals by its graphical output. An example of Z1 lateral for surface point irrigation (variant 2) is presented. The final result of the design calculation is given in the table presenting the most important outputs, including statistic evaluation of the discharge distribution uniformity. A table is presented for surface point irrigation - variant 2. From the table is it clear that hydraulic requirements as well as discharge distribution uniformity from the orifices on the laterals have been fulfilled.
