A rainfall simulator was used to derive curve numbers for a range of antecedent soil water contents and surface cover conditions for an Alfisol soil in the semi-arid tropics of India. These relationships between cover and curve number are compared with relationships that were obtained using model calibration in Part I of this paper. Curve numbers derived from rainfall simulators were similar to those obtained from model calibration. This has improved confidence in using rainfall simulation to measure a runoff curve number.
