This study was carried out during May and June 2010 in the Demonstration Farm of the Faculty of Agriculture, University of Khartoum at Shambat, to evaluate water distribution under different types of sprinkler heads. The study consisted of evaluating Christiansen coefficient of uniformity (CU %) and uniformity of distribution (DU %) under twin nozzle brass impact sprinkler (JIS2), twin nozzle plastic sprinkler (DAN4455) and single. nozzle plastic sprinkler (LEGO55). The twin nozzle brass sprinkler gave significantly better values for all sprinkler configurations, while the difference between twin and single nozzle plastic sprinklers was mostly insignificant. At low wind speeds ( 2.0 m/s) and narrow configurations, the single nozzle plastic sprinkler gave better values of CU% and DU%
