The need to increase irrigation's flexibility and efficiency has led to the development of a more advanced pressurized irrigation. Taking measures to improve water conservation is of particular importance because the on-going demand for irrigation water may lead to an increase in pressure on water sources. Sprinkler irrigation is the process of applying water in the form of a spray in the form of rainfall. Both distribution uniformity and coefficient of uniformity result in approximately the same values when uniformity is high. During applying irrigation water for crops in sprinkler irrigation water mostly lost by wind speed in the form of evaporation. It is affected by the direction and magnitude of the prevailing wind. The other factor which affects the uniformity of sprinkler irrigation is raiser height, mainly in windy areas. As the riser height decreases, water application uniformity will increase and also evaporation and drift losses will increase. They have little or no effect on distribution pattern for wind speed of less than 4 m.p.h. Angle of Wind with Respect to Lateral Line has also an impact on the distribution of irrigation water. A better pattern can be obtained when the wind angle is between 15 to 45 degrees with the lateral. Water pressure at riser has also an impact on the distribution of water in sprinkler system equipment. As the higher pressures are superior, and the slope of the line is less, it indicates that as wind velocities increase the effect of pressure is more prominent. It is recommended that a sprinkler head is operating within the manufacturers recommended range of pressures the uniformity of irrigation can be attained.
