Abstract
A Multiple-input single-output time-invariant, non-linear model, based on a black-box systems approach, was used for how forecasting during monsoon fl ood events using daily data. The model consists of a non-linear component r epresenting the immediate and moderately delayed responses and a linear com ponent representing the delayed response of the catchment. It is based on a structure originally proposed by Muftuoglu, R.F. (New models for nonlinear catchment analysis. J. Hydrol. 73 (1984) 335-357; Monthly runoff generatio n by non-linear models. J. Hydrol. 125 (1991) 277-291). The spatial variati on in rainfall amounts is incorporated in the model by treating the rainfal l as separate lumped inputs. The model, in its non-parametric form, is firs t calibrated on various data sets stacked together and then verification te sts are performed on different data sets. The results show that the model i s capable of forecasting flows with high efficiencies for the data used, in dicating that it provides a low cost alternative model for use in sparse-da ta scenarios and for small-one-off projects.
