O método inverso na determinação da condutividade hidráulica não-saturada para fins de irrigação por gotejamento.

Abstract

The inverse method is presented for determining the unsaturated hydraulic conductivity, K(h), of a silt loam soil under point source and steady-state flow. Water content and matric potential (h) were monitored in the soil profile, at 24 radial positions from a 0,43 l.h-1 dripper. Results showed that the inverse method gives an extended determination of K(h) and the success of the method is highly dependent on the accuracy of the fitted model.
