Abstract

The discrete state space representation of the Kalinin-Miljukov model was used as the basis for a multilinear discrete cascade flood routing model. The time distribution scheme of model inputs was employed in the setup of the multilinear model and the travel-time parameter of the model was allowed to vary with discharge. The relationship between travel-time and discharge for a reach of the Hron River between Brezno and Banska Bystrica was studied. Empirical models of that relation have been considered that would fit the data and would be consistent with the physical interpretation of the factors determining the relation. Seven such fitted empirical models were used to model the variability of the time parameter in the discrete state space representation of the Kalinin and Miljukov model. The performance of the multilinear model was verified on five flood waves. The modelling results showed that the inclusion of empirical information on the variability of the travel-time with discharge enables satisfactory accuracy of the prediction of the flood propagation process without needing to calibrate the model on pairs of input-output hydrographs. The choice of an appropriate travel-time discharge relationship was briefly discussed.
