ECONOMIA DE ÁGUA EM IRRIGAÇÃO POR ASPERSÃO BASEADO NA DEFINIÇÃO DA VELOCIDADE DE INFILTRAÇÃO

Abstract

Using data from basic speeds of infiltration (VBI), obtained in soils of Coastal Tabuleiros the city of Mal. Deodoro, for aluminum and speed of infiltration for projects (VIP), calculated using the techniques Fashion (Mo), Medium Harmonic (MH), Geometric (MG), simple arithmetic (MAS), Quadrática (MQ), Cúbica ( MC) and Biquadrática (MB), in addition to the Median (Md), was carried out studies on water-saving irrigation by sprinkling compared to the volumes obtained on the basis of these techniques and there is the potential for the runoff. It was the conclusion that the economy of water increased in the following order of technical definition of VIP: MB, MC, MQ, BUT, MG, Md, MH, Mo. Thus, the technical definition of the VIP which saves more water for irrigation is the Fashion.
