Determinação analítica da performance da irrigação por sulcos abertos e em declive.

Abstract

An analytical solution was developed to evaluate free-draining sloping furrows based on Walker and Skogerboe (1987) Volume Balance approach (Lima Filho, 1996). Its application allows to obtain the system performance mathematically instead of a graphical analyses. Field data collected at the “Fazenda Experimental do Vale do Curu da Universidade Federal do Ceará”, show that the analytical solution may be used instead of Walker and Skogerboe (1987) methodology with more acurated results.
