| | Summary: |
| | Hydrological models are developed to simulate the catchment response from
the meteorological data and have numerous practical applications. The hydrologic
models are also frequently applied in the assessment of the climate change impacts to
provide hydrologic simulations with projections of climate variables under some
specified climate change scenario. To obtain reliable projections, robust hydrologic
models are required. Model efficiency is usually quantified in terms of the performance
measures or hydrologic signatures such as mean flows, flow duration curve or seasonal
runoff distribution. The timing of runoff is rarely considered as a signature although it is
of crucial importance when assessing the effects of climate change such as the earlier
occurrence of floods. In this paper, we evaluate the performance of the hydrologic model
for the Toplica River basin in reproducing different signatures including the runoff
timing. The results show good model performance, which is, however, not supported by
the agreement of the observed and simulated runoff timing indicators. We therefore
strongly suggest enclosure of these timing indicators in a model evaluation procedure,
especially for the models intended for assessment of climate change impacts. |
