This study was attempted to evaluate infiltration methods based on irrigation advance for furrow
irrigation. Irrigation advance data were collected at Latif farm, Sindh Agriculture University, Tandojam
for three irrigation events. To achieve the objectives of the study two different methods viz. Upadhyaya
and Raghuwanshi and Valiantzas one-point, were tested against the two-point method. Evaluation of
employed methods was undertaken to know the best method for the prediction of cumulative infiltration
and advance. The results revealed that Upadhyaya and Raghuwanshi (ME=-5.25) and Valiantzas onepoint
(ME=-0.99) are unsuitable for silt loam soil with their original constants as these methods show
great scatter when compared with reference method and measured data. Thus, it is suggested that these
methods must be evaluated before use.
