Uniformidade de distribuição de água em aspersores no projeto de irrigação de rodelas, Bahia.

Abstract

The Christiansen uniformity coefficient (CUC) of a sprinkler irrigation system under different spacings and service pressures on CODEVASF at Rodelas, BA, was determined. Results showing that CUC was not much affected by pressures at a same spacing. However, when spacing increased, independent of pressure, water uniformity distribuition decreased. Only at the spacing of 12 x 12m, under any pressure, CUC was around 80%, adequated limit established to sprinkler irrigation.
