The present paper focuses on the point irrigation design for crops and vegetables on an experimental area of 2,432 square m at Buchel locality, Northern part of Gobi desert in Mongolia. An underground water source (drill hole, well capacity: 2 L/s, water temperature: 10 deg C) and electricity were available in the locality of the selected area of 1 ha and 0.2% grade of slope. The design of the surface and subsurface point irrigation for an area of 128 square m is shown together with a brief description of the hydraulic materials used for the development of the original HYBOZAM programme (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, 20 m lengths each) was used to provide suitable irrigation uniformity from the orifices on the laterals. The HYBOZAM programme provides a visual evaluation of the discharge distribution uniformity from the orifices on the laterals by its graphical output. Hydraulic requirements as well as discharge distribution uniformity from the orifices on the laterals have been fulfilled.
