Abstract : For a large number of practical applications there is a requirement to have a streamflow forecasting model that requires no calibration, that is based upon readily available map based data sources and which can be capable of being mounted on a personal computer. Predictions from the model are shown to be consistently better than MILHY in the two important areas of estimating time to peak discharge and the magnitude of the peak discharge itself. An extensive sensitivity analysis of the model is undertaken and it is shown that it is robust against errors in the input parameters. This is the more encouraging when the model structure developed here is shown to out perform MILHY in selected discharge predictions, in which MILHY is tuned for optimal performance by the selection of curve numbers by back calculation.
