| Abstract: | Rainfall runoff hydrographs for 12 river basins ∼103 km2 in area, simulated using land surface model SWAP, are compared with analogous hydrographs obtained using hydrological models
that took part in the International Model Parameter Estimation Experiment project and demonstrated the best results. All models
were calibrated against data on daily river runoff from each basin over a 20-year period (1960–1979). Optimized model parameters
were used to simulate runoff hydrographs for the following 19 years (1980–1998). The comparison of the modeled hydrographs
for 12 basins in different calculational periods demonstrated that the SWAP model can simulate river runoff with an accuracy
comparable with that of hydrological models. |
