Uniformidade de distribuição de água por aspersão convencional na superfície do solo.

Abstract

Taking in consideration the significant productivity of irrigated areas, and, the different methods to apply same it, to have a knowledge of the alone water distribution, as much above how much below of its surface if it becomes of great importance for the planning of irrigation systems. The experiment was lead in urban area in the city of Cascavel, Paraná, in which 40 irrigations in two spaced sprinklers of 6 meters between itself had been followed, to determine the water distribution, had been used as evaluation parameters, the Coefficient of Uniformity of Christiansen (CUC), and the Efficiency Standard of HSPA (UDH). :The averages of the evaluated parameters respectively for the spacing of 6m x 6m and 6m x 12 meters, had been of 85,4 % and 65,65 % for the CUC, and 75,44 % and 39,77 % for the UDH, respectively. Ahead of these results, we conclude that the system using the spacing of 6m x 6m, showed to a water distribution uniform, presenting a considered performance satisfactory.
