	Summary:
	In the past sixty years several methods for the assessment of rainfall distribution over the surface has developed, but the method proposed by Christiansen is mostly used. Depending on the type of simulator, type of the nozzle and the size of a surface, Christiansen’s coefficient varie from 0.6 to 0.95. This paper presents a method for determining Christiansen's coefficient of uniformity and assessment of its ambiguity due to measurement uncertainty of associated equipment. Rainfall intensities of up to 3.1 mm/min with a uniformity coefficient up to 0.85 can be achieved with this simulator.
