Abstract

The necessity to generate time series of runoff for planning and design purposes and environmental protection at ungauged sites is often the case in water resources studies. As in the case of the absence of measured runoff optimisation techniques cannot be used to estimate the parameters of rainfall-runoff models, regional estimation methods are used instead. In previous studies usually regression methods were used for relating the model parameters to the catchment characteristics in a given region. In the paper a different method for the regional calibration of a monthly water balance model is proposed for the case of sparse runoff data. Instead of using the regional regression, the method involves the regional calibration of a monthly water balance model to several gauged catchments in a given region simultaneously. These catchments were pooled together using cluster analysis of selected basin physiographic properties. For the model calibration a genetic programming algorithm was employed and two problem specific fitness functions were proposed. It is expected, that the regionally calibrated model parameters can be used in ungauged basins with similar physiographic conditions. The performance of such a regional calibration scheme was compared with two single site calibration methods in the Záhorie region of West Slovakia.
