N2 - The research included studying the effect of each of the size of catch cans and the spacing between them on the calculation of water distribution uniformity coefficient and with different spacing between sprinklers and for several sprinklers heads, The research included conducting 10 tests, each test of a different sprinkler head, which included finding three patterns for water distribution along a ray, each representing a radius of a circle of wetness at its center, using different sizes of catch cans, where for each ray there is a different diameter of catch cans. And 480 patterns were found to distribute the field sprinkler irrigation water to cover the sizes and spacing of the catch cans and the spacing between the sprinklers and the different sprinkler heads. The research showed that when the water distribution pattern is symmetric around the sprinkler and there is no wind; there is no effect of the diameter of the catch cans on each of the water distribution pattern along the ray, which represents the radius of the wetness circle, its center is the sprinkler, the uniformity coefficient UC and the distribution uniformity coefficient DU. And both the distribution uniformity coefficient UC and the distribution uniformity coefficient DU increases with the increase of the spacing between the catch cans. Two equations were also devised to express the uniformity coefficient UC and the distribution uniformity coefficient DU at the spacing of catch cans (1 m * 1 m) as a function of each of them at greater spacing between catch cans..
