Estimation of FAO Blaney-Criddle b factor by RBF network

This technical note presents the application of a Radial Basis Function (RB F) network to estimate the FAO Blaney-Criddle b factor. Tabular b values ar e given in the United Nations Food and Agriculture Organization Irrigation and Drainage Paper Number 24. The b values obtained by the RBF network are compared to the appropriate b values produced using regression equations. T he RBF network predicted b values better than the regression equations. An example is given to illustrate the simplicity and accuracy of the RBF netwo rk for b factor estimation.
