A simple power function with R2 greater than 0.99 was fitted to the measured advance data. A procedure based on volume balance principles that used measured advance, advance exponent and Manning 'n' was formulated to evaluate Kostiakov infiltration equation parameters for level basin irrigation. Using ring infiltrometerderived and volume balance-derived infiltration parameters, advance curves for level basin irrigation were simulated. The volume balance-derived infiltration parameters produced curves that agreed well to the observed advance curves with a difference of ± 0.1 minutes in the total advance time. In the case of ring infiltrometer-derived infiltration parameters, deviations of -6.9 to ± 19.4 minutes were found in the total advance time. The study concluded that the infiltration characteristics obtained from the advance data represent the field conditions accurately.
